FInd out number of occurrences of a number in an array using C

Question

In a class they will give some set of students height and we need to calculate number of occurrence of the particular height;

EG::: input(54,55,40,48,54,54)
if they give 54 your program should return 3
if they give 40 your program should return 1
if they give 60 your program should return 0

Answer 1

What you need is the array, size of the array and the value to be searched. Just run the loop from zero to end and count if numer exists....

Sample function

int count_occur(int a[], char exists[], int num_elements, int value)
{
    int i, count = 0;

    for (i = 0; i < num_elements; i++)
    {
        if (a[i] == value)
        {
            if (exists[i] != 0) return 0;
            ++count; /* it was found */
        }
    }
    return (count);
}
