C command line arguments input

enter image description here

Hi! So I was playing with command line arguments to get used to work with them. I tried to make the program to say valid if the argument I would write is the same as the one saved in the variable.
Any ideas why this doesn’t work?

>Solution :

Use strcmp to compare strings.
In C, you cannot use == and != to check for string equality.

What you want is:

if (strcmp(argv[1], pass))   // Use String Compare (strcmp) to test equality.  
                             // Returns 0 if strings are equal
                             // Returns non-zero if strings are different.
{
    printf("Invalid\n");
}
