C :

#include <stdio.h>
int a, i, r;
int main(void) {
    for (i = 1; i <= 15; i++) {
        scanf("%d", &a);
        r += a == 100;
    }
    printf("%d\n", r);
    return 0;
}

C++ :

#include<iostream>

using namespace std;

int main()
{
	int n,b,a;
	a=0;
	for (int i=1;i<=15;i++)
	{
		cin>>b;
		if (b==100)
		a++;
	}
	cout<<a<<endl;
	return 0;
}

Python :

# coding=utf-8
s = input(). split()
r = 0
for i in range(0, 15) :
    r = r + int(int(s[i]) == 100)
print(r)
