Problem in project .exe file

Everything is working perfectly but do not know this project.exe is giving me error. I tried to build new projects but still having same problem. Such a crazy headache......... :(

CDirection issue Solved

Hi friends
                 Sorry for CDirection issue. I did something wrong. Actually I forgot to use namespace. That's why I was getting error. Anyways it is solved.

Thank you

Getting CDirection Error

Hi friends
                I am doing my CMenuItem. I updated the cuigh.h as on wiki page but I am getting an error "Cdirection is not defined" in Cframe.h. But it is prototype in cuigh.h as
"enum CDirection {centre, left, right, up, down};

Can somebody help me with that. Looking forward for reply

Thanks

Convert Bits value of a variable(any type) to Hex

Program is written in the purpose of Converting Bits value of a variable to Hex

#include <iostream>

using namespace std;

void bitDump(void* address, unsigned int size);

int main(){
  long double ld = 12345.123456;
  bitDump(&ld, sizeof(ld)); // print the bit pattern (cool if formatted)
  return 0;
}
//Loop through size and convert each char to 8 binary digits.
void bitDump(void* var, unsigned int size){
    char* addres = (char*) var;
    int count = 1;
    for(int i = 0; i < sizeof(size); i++){
        unsigned int mask = 1 << 7;
        while(m){//convert each char to 8 binary digits
            printf("%d", !!(addres[i] & mask));
            m = m >> 1;
           
            if(count == 4)
            {
                putchar(' ');
                cnt = 1;
            }
            else
            {
                count++;
            }
    }
    putchar('\n');
}

BitPrint Function

Function to Print the Bits of a variable.....

void prnBits(unsigned int val)
 {
    unsigned int m = 1 << sizeof(val)*8 - 1;
   
    while(m)
    {
        printf("%d\n", (val & m) && 1);
        m = m >> 1;
    }
 }

SetBits Function

Fuction to set bits on given no of bit

void setBits(unsigned int&, int BitNo, bool value)
    {
        if(value)
         {
            v = v | (1 << (BitNo - 1));
         }
         else
         {
            v = v & ~(1 << (BitNo - 1));
         }
    }

Update cuigh.h and frame.h

Hi friends
                 I update the cuigh.h and frame.h in the master and did pull request. Please have a look on code and let me know about if it has any problem.

C_BUTTON_HIT key

         As given information in the CButton Implementation specification. The C_BUTTON_HIT Key is not defined in "cuigh.h" class. Can anybody let me know about this issue.

Thanks
Pankaj Sama

0.2 Milestone

Done with Mock up classes and wiki team page. Learn new things like compilation of program without having code. Which is good for coming future in programming. :)

Got account on GitHub

Very excited (`-`)

OOP344 Project 0.1 Completed

I am very happy because I have done OOP344 project 0.1 on time. I learned a lot from this assignment. Also we have a really good Professor.
//Cheers

Project 0.1

Having trouble with ptoject while compling.....i do not know what is going on....having stupid kinds of errors....

END Key

Working on END key...but having lot of trouble with coding...but still trying to complete it as soon as possible....

OOP344 Week 3 to do

I tried a lot to make it in another way. But it is only done by this way..

X-mover:

    case RIGHT:
        if(col == console.getCols()-2 && row == console.getRows()-1){
        console.alarm();
      }
        else if(col < console.getCols()-1){
        col++;
      }
      break;
     
    case DOWN:
      if(row == console.getRows()-2 && col == console.getCols()-1) {
        console.alarm();
      }
      else if(row < console.getRows()-1){
        row++;
      }
      break;

   


Removing if else statement from console.display() function.. It is done by condition operator

    void Console::display(const char* str, int row, int col, int fieldLen){
      setPos(row, col);
      int i;
      int lenght;
      lenght = strlen(str);
       
        for(i=0,fieldLen==0?fieldLen=lenght:i=0;i<fieldLen;str[i]!=0?putChar(str[i]):putChar(' '),i++);
    }

Xmover project

I am so happy...because I fixed Xmover to do in my OOP344 project

Project 0.1

It is really challenging for me because I do not have any previous experience.....
trying hard to finish it as soon as possible...but overall it is very interesting to do.... :)

OOP344 week 2 Exercises

1. Sum of two numbers by command line

#include<iostream>

#include<stdlib.h>

using namespace std;

int main(int argc, char* argv[])

{

        int sum;

        if(argc == 3)

        {

                cout << "Sum of the number is: "<< atoi(argv[1]) + atoi(argv[2]) << endl;

        }

        else

        {

                cout << "Please enter thr correct input" << endl;

        }

        return 0;

}

2. Subtraction of two numbers by command line

#include<iostream>

#include<stdlib.h>

int main(int argc, char* argv[])

{

        int sum;

        if(argc == 3)

        {

                cout << "Sum of the number is: "<< atoi(argv[1]) - atoi(argv[2]) << endl;

        }

        else

        {

                cout << "Please enter thr correct input" << endl;

        }

        return 0;

}

3. Multipication of two numbers by command line

        if(argc == 3)
        {
                cout << "Sum of the number is: "<< atoi(argv[1]) * atoi(argv[2]) << endl;
        }
        else
        {
                cout << "Please enter thr correct input" << endl;
        }
        return 0;
}

#include<iostream>
#include<stdlib.h>

using namespace std;

int main(int argc, char* argv[])
{

        int sum;

        if(argc == 3)
        {
                cout << "Sum of the number is: "<< atoi(argv[1]) / atoi(argv[2]) << endl;
        }
        else
        {
                cout << "Please enter thr correct input" << endl;
        }
        return 0;
}

Working on programming question given by my professor..........

First day in OOP344 class....

Hi everyone
                    I want to share my experience of programming in Seneca College. Please give me comments and any relevant information related to OOP344.

Thanks
