return 0;

Answer 1

Your first mistake u forget #(hash) in headerfile your int main int should be in small letter .
after that where you write if condition here u used assignment operator this is wrong u have to give exact condition .
You cannot assign values in u should use == double equal to .
In c and cpp single quotes and double quotes have difference to single quotes denote char and double string you define char a and in if condition u wrote
'12ab' this is invalid
. This is string you should write it on double quotes
'a' char and this "12ab" is string .
Next you cannot compare string directly in c and cpp you should use
strcpy() function

for comparison.
