现在我想将存储在赎金中的字符串与杂志进行比较。怎么做？请帮忙

Answer 1

您可以在循环中使用strcmp：

for (i = 0; i < n; i++) {
    if (strcmp(magazine[i], ransom[i]) == 0) {
        ...
    }
}

但如果（如标题所示）ransom被声明为指向char的指针：

char **ransom;

您不希望取消引用运算符*

*ransom = malloc(sizeof(char*) * n);

应该是

ransom = malloc(sizeof(char*) * n);

如何比较两个字符串，它们（两个）都存储在char双指针中？
