我想知道fgets()和之间有什么区别scanf().我使用C作为我的平台.

noob问题:我正在尝试编写一个简单的菜单界面,但我不断收到分段错误,我无法弄清楚原因.

int edit(char *name, char *password, char *type, char *newName, char *newPassword, char            *newType);
int verify(char *name, char *password);



int menu(){

    printf("MAIN MENU \n ============\n");
    printf("1. ADD\n");
    printf("2. DELETE\n");
    printf("3. EDIT\n");
    printf("4. VERIFY\n");
    printf("5. Exit\n");
    printf("Selection:");
    scanf("%d", &input);
    flush();
    switch (input){

    case 1:
        printf("%s\n", "Enter Name:");
        scanf("%s", name);
        flush();
        printf("%s\n", "enter password" );
        scanf("%s", password); …
