Science fair project brute force password cracker

Warmaster1116 (1)
iv been trying to find out my errors but i'm confused on what i'm doing wrong.
i'm using code blocks with the GNU GCC compiler. is the issue the compiler, code blocks, or just my own ignorance? This is for a science fair project that is due in April of 2017.

Presenting the errors produced by the compiler might be a start. On line 10, what are you setting pass equal to?

Semi-colons are not needed to terminate compound statements.

if ( some_condition ) {
    // some code here.
} ;  // <- semi-colon is superfluous and may cause an error when you go to add an else clause


= is assignment. == is comparison.

x = while ( some_condition ) { /* some code */ } is not valid syntax. What is the result of a loop?

Line 95 is wrong. Adding a char to a char results in an integer value, not a string.
