This is Day7 of30 in Solidity Series
Today I Learned About Functions in Solidity.

A function is basically a group of code that can be reused anywhere in the program, which generally saves the excessive use of memory and decreases the runtime of the program. Creating a function reduces the need of writing the same code over and over again.

Syntax -

functionfunction_name(parameter_list)scopereturns(return_type){// block of code}

eg-

// SPDX-License-Identifier: MITpragmasolidity^0.8.7;contractMyContract{functionadd()publicviewreturns(uint256){uint256num1=10;uint256num2=16;uint256sum=num1+num2;returnsum;}functionsqrt(uint256num)publicpurereturns(uint256){num=num**2;returnnum;}}

view in a function ensures that they will not modify the state of the function.
