Question

In C language:

Write the fnFindMin function which can receive a float array, an integer number(number of elements) as input arguments and finds the minimum value in the array. This function should return the array index (subscript) of the minimum value.

Answer 1

C code:

#include <stdio.h>
//initializing fnFindMin function
int fnFindMin(float numbers[],int n){
//initializing minimum element as the first number
int min=numbers[0];
//initializing index of minimum element as 0
int min_index=0;
//loop to check all numbers
for(int i=1;i<n;i++){
//checking if the current element is less than min element
if(numbers[i]<min){
//initializing current element as min
min=numbers[i];
//initializing min_index as current index
min_index=i;
}
}
//returning min_index
return min_index;
}
int main()
{
//initializing a sample array containing numbers
float numbers[]={2.1,3.2,1.1,5.1};
//calling fnFindMin function
printf("%d",fnFindMin(numbers,4));
return 0;
}
