Can anyone tell me how to calculate frequency of each array elements in c?

Question

eg 12342628569 :- here frequency of 2 is 3

Answer 1

Frequency of 2 is not 3, it is 3/ size of array == 3/11

double freq(int * array, unsigned size, int value){
double res = 0.;

if(array && size)
for(unsigned i = 0; i < size; ++i)
if(array[i] == value)
res += 1;

return size?res/size:res;
}

if you wanted to know the number of time the value appears in the array, change double to unsigned and change the return line by :
return res;
