Generally, in every C program, we include at least one header file stdio.h. The functions like printf and scanf, which we are regularly using in our program, are defined inside stdio.h header file. So the purpose of including stdio.h is to add the definition of these functions into our program. Now, can we write any

The scope of variables in C language is the portion of the program where the program can be referenced. For example, when we define a local variable in a block, it can be referenced only following its declaration in that block or in blocks nested within that block. The two identifier scopes are block scope
