Thread: Replace elements of array C with units

I have a one-dimensional array in which I need to replace the elements of the array after the smallest element with one and find the sum of all the elements before the smallest element, but I don't know how to do it, please help.

Code:

#include <stdio.h>
#include<stdlib.h>
void main()
{
 float X [16]={2.34, -3.42, 0.56, -3.71, 1.25, 6.37, 0.123, -45.821, 32.5, 0.94, 0.54, -1.26,
2.36,  4.32, -5.345, 4.876 };
 int sum;
 float min;
 float Y[16];
     printf("massif Х\n");
  for(int i=0;i<16;i++){
     printf("%2.3f\t",X[i]);
}
  for(int i=0; i<16; i++){
    if(min>X[i]){
    Y[i]=X[i]; 
    min=X[i];
} 
    }printf("\nMin = %2.3f", min);


}

A couple of things
- The main procedure returns an int and has to be declared accordingly.
- The corresponding closing brace ends the main procedure. Look where it is in your code. Count opening and closing braces and ensure they are balanced. (Proper code indentation helps a lot.)
- Initialize sum with 0 to be able to add the value of an element in each iteration of the loop. Consider to declare sum a float rather than an int.
- Initialize min with the first element (at index 0) in order to have a value to compare with.
- Declare another variable as int (e.g. indexOfMin) and initialize it with 0. Use it to remember the index of the current min value that you found.
- You don't need the Y array. You know now the index of the smallest element and thus, you can perform the replacement in the original array.
