Thread: Hai to all

Try making the line to print something like

Code:

printf("sum=%d\n", d);

With the newline, it should print the result - if there's no newline, printf may well end up being buffered, and thus not showing up before the application finishes (and being lost completely).

An alternative problem is if you are running this from a IDE where the "application" window disappears before you have time to read the text - in which case you need to add something to stop it from "going away" before you have seen the end of it. adding

Code:

system("pause");

at the end of the code would do that.

Also: "main" is a function that returns "int", so you should really not make it a void function - and you should return something at the end of the function (customarily zero to indicate success - other return values customarily indicate failure).

It is indeed so - the only problem with this approach is that it also involves explaining how to get rid of the remaining newline in the buffer after scanf(), and for two reasons, I suggested the "system(pause)" solution as a "better" alternative:
1. I think the poster is quite new to programming - and adding a "flush the input buffer" would mean adding some relatively complicated code to the application.
2. I'm lazy - just simpler to suggest the "shorter to type" answer. At least I'm honest about it ;-)

use getch(); in the program

Code:

#include<stdio.h>
void main()
{
  int a,b,sum;
  printf("enter two numbers\n");
  scanf("&#37;d %d",&a,&b);
  sum=a+b;
  printf("sum=%d", sum);
  getch();
}

the use is to see the result in run time
in your program you can see the result by pressing alt+F5 after compiling the program

files are closed and flushed on program shutdown.
