For example, to declare an integervariablecalled“x,”you can use: intx; Todeclare multiple variablesof the same type simultaneously, you can write like this: intnum,num1,num2; How to Define a Variable in C Programming? After the variable declaration, you must assign a value to a variabl...
Before using the function pointer we need to declare it and the prototype must be similar to the function which addresses you want to store. In the below example, I want to store the address of a function (AddTwoNumber) which takes two integers as an argument and returns an integer. ...
Function in C: Functions are a group of various statements that perform a task together- also known as sub-routine or a method or a procedure. The standard library in C language provides its users with various built-in functions that the concerned progra
If we are unable to use the assert() function, we must be disabled, so ndebug should be defined. It was decided to declare it using #define NDEBUG code; otherwise, the code compilation should pass. -NDEBUG in the code. The code compilation will pass -DNDEBUG to disable the assert() fu...
