#include <iostream>

ERROR: In function `int main()':
no match for 'operator==' in 'b == 1'

b is a string. It contains text. You can't compare it with a number. If the string contains a number in text form then you need to either convert the string to a number or the number to a string before you compare them.

can somebody help please if possible.....
the problem is
i assigned b as integer and there is some problem in if statement when i compile the program instead of output
"January" it is out putting some random integer numbers.....

Are you sure that b needs to be a string in the first place? a and c are both integers.

Also I don't think you ever give b a value before you test it.
