在 c 中使用 scanf 获取动态数组的用户输入

Question

When I try to get user input for the dynamic array, it stops at the first for loop. It gives me an error that my program has stopped working. Help me out!

#include<stdio.h>
#include<stdlib.h>

int main(){
    int count = 0, sum = 0, *number = NULL, index = 0, size = 0;
    scanf("%d", &size);

    number = (int *)calloc(size, sizeof(int)); //Dynamic allocation

    printf("Enter the elements\n");
    for(index = 0; index < size; index++){
        scanf("%d",number[index]); //Getting the input values from user but i get an error
    }
    return 0;
}

Answer 1

Use this instead:

scanf("%d", &number[index]);

Note the & operator before number[index] is needed when using scanf for integer input.
