[C] Integer Type Input/Output

• scanf : Formatted Read
• printf : Formatted Write

#include <stdio.h>

int main(void)
{
    int a, b;
    puts("-----------------------------");
    puts(" ** Integer input / Output");
    puts("-----------------------------");
    
    printf(" Input : ");
    scanf("%d %d", &a, &b);
    
    printf("a=%d, b=%d \n", a, b);
    
    return 0;

    /*
    -----------------------------
     ** Integer input / Output
    -----------------------------
     Input : 1 5
    a=1, b=5
    */
}

#include <stdio.h>

int main(void)
{
	int a, b;
	puts("-----------------------------");
    puts(" ** Integer input / Output");
    puts("-----------------------------");
    
    printf(" First integer : ");
    scanf("%d", &a);
    
    printf(" Second integer : ");
    scanf("%d", &b);
    
    printf("a=%d, b=%d \n", a, b);
    puts("-----------------------------");
	
	return 0;

    /*
    --------------------------
     ** Integer input / Output
    -----------------------------
     First integer : 1
     Second integer : 2
    a=1, b=2
