An integer (>=3) representing the total number of houses that you visited.

Output Format
A percentage value rounded up to the nearest whole number.

Answer 1

you should have used ceil function from math.h header to round up final value

Answer 2

Attach the code what you tried

Answer 3

#include <stdio.h>

int main() {
int houses;
int a;
scanf("%d", &houses);

a=200/houses;
//your code goes here
if (200%houses==0)
printf("%d", a);

else
printf("%d", a+1);

return 0;
}
this is without using math header file
