We will discuss about Nesting of function in C programming language
When one or more functions are utilized under a particular function, it is known as nesting function in C Programming Language.
Note – We can not define a function within another function in C language(nested function is not supported by C language). we can only declare a function within another function in C(not define).
We can declare of the nesting of function as follows
int main(){//main function in C
return_type function_name();//Call function under the main function
return 0;
}
return_type function_name(){//user defined function //statements of function
}
//nesting function in C language return_type function_one()
{
statements
// statements of function_one
function_two();
//called the function_two inside the function one
}
return_type function_two() //declaration of function two
{
statements
// statements of function_two
function_three(); //called the function_three
}
return_type function_three()//declaration of function three
{
statements
// statements of function_three
}
int main()
{
function_one(); //called the function_one
return 0;
} Example 1
#include <stdio.h>
#include <stdlib.h>
int main()
{
printf("This is main method in c\n");
function_one();
getch();
return 0;
}
void function_one()
{
printf("This is a user define function\n");
function_two();
}
void function_two()
{
printf("This is nested function in c\n");
}
When the above code is executed, it produces the following results:
This is main method in c This is a user define function This is nested function in c
At the above program, we have created two functions with its statements. Then we declare function_two inside the function_one. Afterwards, when we call function_one under the main function, statements for both function_one and function_two are displayed.
Example 2
#include <stdio.h>
#include <stdlib.h>
int main()
{
printf("world countries\n");
India();
getch();
return 0;
}
void India(){
printf("I am india in asia\n");
Srilanka();
}
void Srilanka(){
printf("I am srilanka near the india\n");
printf("I am one of small country in asia\n");
Nepal();
}
void Nepal(){
printf("I am nepal near the india\n");
printf("I am beauty in asia\n");
China();
}
void China(){
printf("I am china in asia\n");
printf("I am powerful in asia\n");
}
When the above code is executed, it produces the following results:
world countries I am in India in Asia I am in Srilanka near the India I am in a small country in Asia I am in Nepal near India I am beauty in asia I am china in asia I am powerful in asia
Example 3
#include <stdio.h>
#include <stdlib.h>
int cube(int a)//cube function
{
return a*a*a;
}
void display()//Function to display
{
int i;
for(i=1; i<=10; i++){
printf("cube value of %d is %d\n",i,cube(i));
}//cube function called inside the display function
}
int main()
{
display();
getch();
return 0;
}
When the above code is executed, it produces the following results:
cube value of 1 is 1 cube value of 2 is 8 cube value of 3 is 27 cube value of 4 is 64 cube value of 5 is 125 cube value of 6 is 216 cube value of 7 is 343 cube value of 8 is 512 cube value of 9 is 729 cube value of 10 is 1000
Example 4
#include <stdio.h>
#include <stdlib.h>
int main()
{
add();
getch();
return 0;
}
int add() //defined the add function
{
mul(); //declared of mul function
int a,b,c;
printf("Enter two numbers to addition :\n");
scanf("%d %d",&a,&b);
c=a+b;
printf("Addition is :%d\n",c);
return 0;
}
int mul() //defined the mul function
{
int x,y,z;
printf("Enter two numbers to multiplication :\n");
scanf("%d %d",&x,&y);
z=x*y;
printf("multiply is :%d\n\n",z);
return 0;
}
When the above code is executed, it produces the following results:
Enter two numbers to multiplication : 6 5 multiply is :30 Enter two numbers to addition : 20 15 Addition is :35
The nested function is not supported in C language because we cannot define a function inside another function in C language
