Post your C/C++ Programs Here

Gigacore · Sep 2, 2007

Hi guys n gals,

If you are a good at C/C++ Programming or if you are a programmer or just know this language then post you Programs here. By this way it helps learners a lot. Members can post their programs and get suggestions if there is anything wrong it......

Use this Pattern:

A Program to find the largest of three numbers using nested if

Code:

#include <stdio.h>
main()
{    
    int    a,b,c,big;
    printf("Enter Three numbers");
    scanf("%d%d%d",&a,&b,&c);
    if(a>b)
        if(a>c)
            big=a;
        else
            big=c;
    else
        if(b>c)
            big=b;
        else
            big=c;
    printf("Largest of %d,%d and %d = %d",a,b,c,big);
return 0;
}

My Program to calculate Addition

Code:

#include <stdlib.h>
main()
{
float a,b,c,total,multiply,add,input;
printf("Welcome to Demon Calculator \n\n");
printf("Enter the values-\n\n");
printf("a:");
scanf("%f",&a);
printf("b:");
scanf("%f",&b);
printf("c:");
scanf("%f",&c);

total=a*b*c;
if (total>80000)
printf("Meri Marzi , tu khud solve kar.\a\a\a\a\a\a\a\a\a\n\n");
else
printf("The answer is %f\n\n\a\a",total);
system("pause");

Your program lacks proper braces and a return statement.

Your code doesn't conform to either ISO C or C++ standards.

scanf() is a C input function, which is considered unsafe except for formatted data. I advise learning C first, before opting for a much larger, bloated and complex language as C++.

Try this:

Code:

#include <stdio.h>

int main(void)
{	
   int a = 0,
       b = 0,
       c = 0,
       greatest = 0;

   printf("Enter three numbers:\n");
   scanf("%d %d %d", &a, &b, &c);

   greatest = a;
   if(b > greatest)
      greatest = b;
   if(c > greatest)
      greatest = c;

   printf("greatest of %d, %d and %d = %d", a, b, c, greatest);
   return 0;

^^this is totally wrong what if b>c>gr8test there's no condition to test that

use this thread to request programs and then pm to the requester rather than posting so much code over here it really looks a mess and these are quite basic too

Rules of programming:
1. Read the fscking code. And mine is pretty readable.
2. Test it before complaining.
3. If you still don't get it, it's time to buy a decent C book.

Using implementation dependent libraries and functions like clrscr(), and the nonstandard "void main()" violates the rules of the ISO C++ standard. Your executable may run fine on a system, but your code needs more love.

I recommend a decent and recent C++ book, like C++: How To Program, C++ Primer, 4th/e or C++ Primer Plus.
