给字符型数组直接赋值

Question

int get_input_multilan(char **olan)
{
    int rtn = 0;
    char str_lan[128];
    printf("\n\nFor example:1 2 4 (selected segment1, segment2 and segment4).\n");
    printf("Please select segment [{1-8}, {9}]:");
    scanf("%[^\n]", str_lan);

    *olan = xstrdup(str_lan);

    return rtn;
}

请问各位，我想直接赋值一个整数给到 str_lan ，上面这段代码是可行的，但是我想直接给 str_lan 赋整数值，应该怎么写呢？

Answer 1

整数不行啊，你是char[]类型
建议这样

int get_input_multilan(char **olan)
{
    int rtn = 0;
    char str_lan1[128];
    int str_lan;
    printf("\n\nFor example:1 2 4 (selected segment1, segment2 and segment4).\n");
    printf("Please select segment [{1-8}, {9}]:");
    scanf("%[^\n]", str_lan1);
    sscanf(str_lan1, "%d", &str_lan);
    *olan = xstrdup(str_lan);
 
    return rtn;
}
