I want to save the full output of the below C program in a .txt file.

#include<stdio.h>
#include<conio.h>
void main()
{
int a, b, c;

printf("Enter two numbers to add\n");
scanf("%d%d",&a,&b);

c = a + b;

printf("Sum of entered numbers = %d\n",c);
getch();

}

I used the following commands in cmd prompt. But it just shows the printf value alone and not save the scanf value(the keyboard inserted value).

C:\Programs\Ramkumar>sample.exe /all > file.txt

Can anyone provide me the command for the full output to save in txt file.

Thanks in advance.
