Question

我正在尝试复制数组指针并打印复制数组中的值，但是我遇到了分段错误。

void kosomo(char * test[10]) {
        int j=0;
        char * test2[10];
        while (test[j] != NULL) {
                test2[j]=&test[j]; // test[j] is the string, so with & it's the address
                j++;
        }

        printf("%d ",*test2[0]); // trying to do * in order to print the string
}


int main() {
        char * test[] = {"abc","def",NULL};

        kosomo(test);
}

请尝试此程序可以帮助您。我假设您要打印整个字符串数组。

#include <stdio.h>

void kosomo(char *test[10]) {
    int j = 0;
    char *test2[10];
    while (test[j] != NULL) {
        test2[j] = test[j]; 
        j++;
    }
    test2[j] = NULL;
    j=0;
    while (test2[j] != NULL) {
        printf("%s ", test2[j]);
        j++;
    }
}

int main() {
    char *test[] = {"abc", "def", NULL};
    kosomo(test);
    return 0;
}

输出

abc def
