The first c program
Important points about a C program
- Every C program starts with including header files containing library of functions to be used in the program.
- Every C program starts with a main( ) function.
- Every statement in C program must end with a semicolon ;(unless it is a comment)
- A main function defines a single or multiple set of statements to execute within opening and closing braces {}.
To write the first c program, open the Turbo C and write the following code:
#include< stdio.h >
void main()
{
printf("welcome to Tutorial Zone");
}
#include < stdio.h > includes the standard input output library functions. The printf( ) function is defined in stdio.h
Output:
int main() The main() function is the entry point of every program in c language.
printf() The printf() function is used to print data on the console.
