#include <stdio.h> 
int main() 
{ 
    int a = 0; 
    scanf("%i", &a); // input is 017 (octal of 15 ) 
    printf("%d\n", a); 
    scanf("%i", &a); // input is 0xf (hexadecimal of 15 ) 
    printf("%d\n", a); 
    return 0; 
}

This function take input using standard input (keyboard) and store it in variable accordingly. It returns the number of items successfully read. Formal parameter arg1, agr2, .. must be a pointer

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
