Method 1

#include <stdio.h>

int main(void) {
    int a[4], i, j;
scanf("%d %d %d %d", &a[0], &a[1], &a[2], &a[3]);
for(i=0; i<4 ; i++)
{
    if(a[i]>=1 && a[i]<=100)
    {
        if(a[i]>9)
        {
            j++;
        }
        else
            continue;
    }
    else
        continue;
}
printf("%d", j);
return 0;
} 

Method 2

#include <stdio.h>

int main(void) {
    int a[4], i, j;
    for(i=0; i<4 ; i++)
    {

    }
for(i=0; i<4 ; i++)
{
    if(a[i]>=1 && a[i]<=100)
    {
        if(a[i]>9)
        {
            j++;
        }
        else
