How to sort array of numbers in C -

i'm trying sort array using function findminimumindex in loop, can't seem find it's not sorting correctly. suggestions? function works fine, when try use in loop, doesn't work. suggestions? thanks!

int findminimumindex(a[], int a, int b); //finds smallest index of portion of array (a[i] ... a[j])  int main(){     int a[5] = {4,6,7,4,3};     int smallest_index;     (int j = 0; j < count; j++){         smallest_index = findminimumindex(a, j, 4);         printf("sorted: %d\n", a[smallest_index]);     } }  int findminimumindex(int a[], int a, int b){     int smallest_value = a[a];     int index = 0;     (int k = a; k < j - 1; k++){         if (a[k + 1] < smallest_value){         smallest_value = a[k+1];         index = k + 1;         }     }     return index;  } 

if find minimum value , index, should switch values:

look @ example:

you have got array:

{4,6,7,4,3} 

at first, find value 3 @ index 4, have move smallest value (switch value on j=0 index):

{3,6,7,4,4} 

then find 4 on index 3, then, switch j=1:

{3,4,7,6,4} 

etc.

modification of code:

for (int j = 0; j < count; j++){     smallest_index = findminimumindex(a, j, 4);     int tmp = a[smallest_index];     a[smallest_index] = a[j];     a[j] = tmp;     printf("sorted: %d\n", a[j]); } 

edit: correction:

length of array 5:

    smallest_index = findminimumindex(a, j, 5); 

and index should set a

int findminimumindex(int a[], int a, int b){     int smallest_value = a[a];     int index = a;     /*  code */ }
