用C语言打印出动态分配的内存

int* ptr = (int*)malloc(10 * sizeof(int));

if (ptr == NULL) {
    printf("内存分配失败\n");
    return -1;
}

for (int i = 0; i < 10; i++) {
    ptr[i] = i + 1;
}

for (int i = 0; i < 10; i++) {
    printf("%d ", ptr[i]);
}

free(ptr);

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

int main() {
    int* ptr = (int*)malloc(10 * sizeof(int));
    
    if (ptr == NULL) {
        printf("内存分配失败\n");
        return -1;
    }
    
    for (int i = 0; i < 10; i++) {
        ptr[i] = i + 1;
    }
    
    for (int i = 0; i < 10; i++) {
        printf("%d ", ptr[i]);
    }
    
    free(ptr);
    
    return 0;
}
