hey i got to write a program which stores randoms numbers in an array use insertion sort and selection sort and time both of them witht the lcock fnction to see which is faster.how do i use the clock function?? where do i put it?

Code:#include<stdio.h> #include<stdlib.h> #include<time.h> void print(int[]); int random(int,int); void insertionsort(int[]); void selectionSort(int[]); int main(){ int i,arr1[10000],arr2[10000]; srand(time(0)); for(i=0;i<10000;i++){ arr1[i]=random(1,1000000); arr2[i]=random(1,1000000); } insertionsort(arr1); print(arr1); selectionSort(arr2); print(arr2); system("pause"); return 0; } int random(int m,int n){ int offset =rand()/(RAND_MAX + 1.0)*(n-m+1); return m+offset; } void insertionsort(int arr[]){ int j,k,key; for(j=0;j<10000;j++){ key=arr[j]; k=j-1; while(k>=0 && key<arr[k]){ arr[k+1]=arr[k]; --k; } arr[k+1]=key; } } void selectionSort(int numbers[]) { int array_size=10000; int i, j; int min, temp; for (i = 0; i < array_size-1; i++) { min = i; for (j = i+1; j < array_size; j++) { if (numbers[j] < numbers[min]) min = j; } temp = numbers[i]; numbers[i] = numbers[min]; numbers[min] = temp; } } void print(int arr[]){ int j; for(j=0;j<10000;j++){ printf("%d ",arr[j]); } }
