C语有序数组合并的初步实现

void He(int arr1[],int arr2[],int n,int m,int c[]){
    int c1=0,c2=0,r=0;
    while(c1<n&&c2<m){
        if(arr1[c1]<arr2[c2]){
            c[r++] = arr2[c2++];
        }
        else
            c[r++] = arr1[c1++];
    }
    while(c1<n){
        c[r++] = arr1[c1++];
    }
    while(c2<m){
        c[r++] = arr2[c2++];
    }
}

还是比较容易理解的！
