1. What is functional cohesion?
2. What is meant by "each function should do only one thing"?
Explanation / Answer
1. if the function contains or deals directly with integers or any other type of variable then the functions declarations will be similar to variable declarations 2 in functions declarations,all the variables used in function should be declare before they are being used 3 decl-specifiers declarator [cv-qualifers] [exception-specification] { // function body } Function definitions differ from function declarations in that they supply function bodies — the code that makes up the function. 4 at the start of the program 5 All functions in C always use the same basic pattern (syntax). This syntax can be captured in a "Design Pattern". Your job is to memorize this pattern for future use
