Relational Operators in C - GeeksforGeeks
In C, relational operators are the symbols that are used for comparison between two values to understand the type of relationship a pair of numbers shares. The result that we get after the relational operation is a boolean value, that tells whether the comparison is true or false. Relational operators are mainly used in conditional statements and loops to check the conditions in C programming.

C Relational Operators - Online Tutorials Library
All the relational operators are binary operators. Since they perform comparison, they need two operands on either side. We use the = symbol in C as the assignment operator. So, C uses the "==" (double equal) as the equality operator.The angular brackets > and < are used as the "greater than" and "less than" operators. When combined with the "=" symbol, they form the ">=" operator for "greater ...
