Header files: A header file is a file with extension . h which contains C function declarations and macro definitions to be shared between several source files. Main function: In C, the "main" function is treated the same as every function, it has a return type (and in some cases accepts inputs via parameters). The only difference is that the main function is "called" by the operating system when the user runs the program.
Declear Variables:
In C programming, variables which are to be used later in different parts of the functions have to be declared. Variable declaration tells the compiler two things: The name of the variable. The type of data the variable will hold.
string1,i and flag Enter Number : For Loop :
Start from 1 and goes till 10
Printf Function
Each time printf function print the n*i value
Suppose i=3 and n value entered is 5 than this will print the value 15
Exit from the loop Block Exit With Program with returning 0 value
