Question

比较用户键盘输入的口令userInput与内设的口令password是否相同

#include <stdio.h>
#include <string.h>
int main()
{
    char password[7] = "secret";    
    char userInput[81] ;
    printf("Input Password:");
    scanf(_____________);//第8行
    if ( ______________ )//第9行
        printf("Correct password! Welcome to the system...\n");
    else if ( ___________________) //第11行
   
        printf("Invalid password!user input<password\n");
    else
        printf("Invalid password!user input>password\n");   
    return 0;
}

能给个大致思路吗？谢谢!

    char password[7] = "secret";    
    char userInput[81] ;
    printf("Input Password:");
    scanf("%s", userInput);//第8行
    if ( strcmp(userInput,password)==0 )//第9行
        printf("Correct password! Welcome to the system...\n");
    else if ( strcmp(userInput,password)<0 ) //第11行
        printf("Invalid password!user input<password\n");
    else
        printf("Invalid password!user input>password\n");   
    return 0;
