Nesting of function
#include<stdio.h>
#include<conio.h>
void main()
{
Function1();
}
Function1()
{
Function2();
}
Function2()
{
}
As shown in the above
example, Function1() is called from the main function. In the definition of the
Function1(), Function2() is called. Thus, main function calls Function1,
Function1 calls function2 and
Likewise it may
continue. This type of function calls are known as nested function calls. We
have previously studied nested for, nested if, similarly the same concept
applies to the nested functions also.
Consider following example.
Example
#include<stdio.h>
#include<conio.h>
void
getmarks();
void
gettotal(int, int, int);
void
getpercent(int);
void main()
{
clrscr();
getmarks();
getch();
}
void
getmarks()
{
int m1, m2,m3;
printf(“Enter the marks out of
100”);
scanf(“%d %d
%d”,&ma,&m2,&m3);
gettotal(m1,m2,m3);
}
void
gettotal(int m1,int m2,int m3)
{
int total;
total = m1+m2+m3;
printf(“\n The total marks :
%d”,total);
getpercent(total);
}
void
getpercent(int total)
{
float percent;
percent = (total/3);
printf(“\n The percentage is %.2f
%”,percent);
}
