Go through C Theory Notes on Conditional Operators before … In C and C++, return exp; (where exp is an expression) is a statement that tells a function to return execution of the program to the calling function, and report the value of exp.If a function has the return type void, the return statement can be used without a value, in which case the program just breaks out of the current function and returns to the calling one. We can use pointers in C to return more than one value from the function by passing pointers as function parameters and use them to set multiple values, which will then have visibility in the caller function.Download Run CodeOutput:a = 10, b = 20, c = A Pre-requisite: Functions in C/C++ The return statement returns the flow of the execution to the function from where it is called.
