Hi Ashish,

The return type of printf() and scanf() is int

In the declaration, observe the return type is int.

int printf(const char *format, ...);
int scanf( const char *format, ... );


printf() returns the number of charecters printed on the console
scanf() returns the number of variables to which you are provding the input.

The following example will give u the clear idea.

#include<stdio.h>

int main()
{
    int i,j;
    printf("nPrinted %d charecters on stdoutn ",printf("Enter values of i & j"));
printf("nYou entered input for %d variables",scanf("%d %d",&i,&j));
  getch();  
}

#include
int main()
{
char i;
printf("
%c
",scanf("%c",&i));
return 0;

}
Given piece of code gives no output when we give character e as input.
why is it so??

 

Code
#include<stdio.h>


"


%c


",scanf("%c"

Return type of both of them is integer. Scanf returns how many things it has read while printf returns how many characters get printed.
