Introduction to C | Structure of C Program

Prologue to C 

Structure of C Program 

Each C program is made of capacity and each capacity comprise of directions called explanation. 

Structure of C Program. 

#include/stdio.h is the header document 

principle()/primary capacity is the main capacity which is executed by a C program. 

All C articulations are composed inside primary capacity. 

{ 

/All C articulations. 

} 

Capacities 

Each C program comprises of at least one modules called capacities. One of the capacities must be called primary( ). 

The program will consistently start by executing the primary capacity, which may get to different capacities. 

Some other capacity definitions must be characterized independently, either in front of or after fundamental. 

A capacity name is constantly trailed by a couple of bracket, to be specific, ( ). And all capacity articulations are encased inside a couple of supports { }. 

The program execution consistently begins with primary capacity. At the point when the end support of the principle capacity is achieved, program execution stops, and the control is given back to the OS (Operating System). 

Proclamations 

Single C language guidance is known as an announcement. Proclamations are composed by the punctuation of C language. Each C language explanation must finishes with semicolon(;). 

So as to compose a C program we ought to pursue some fundamental standards which are depicted beneath: 

a) Usually all announcements in C are entered in little letters in order. 

b) Blank spaces might be embedded between two words to improve the program comprehensibility. Anyway no clear spaces are permitted inside a factors, constants or watchwords. 

c) It has no particular principles for the situation at which explanations is to be held that is the reason it�s frequently called a free structure language. 

d) All C articulations must end with a semicolon (; ) 

Till now, We have almost no information about the kind of factors, constants and watchwords. Presently we would attempt to comprehend the basic C program.
