Nested Functions

If more than One function is Called in a single line then the principle is

called as ‘Nested Function’.

It is mostly useful when a series of Arithmetical Transactions fall in a Single

Formula.

The Result of a Particular Function need to be DEPENDENT on the

OPERATION carried out by ANOTHER FUNCTION.

Illustrative Example

Program

#include <stdio.h>

void main()

{

int add(int, int);

int sub(int, int);

int mult(int, int);

float div(int, int);

int a, b, c, d, f, g, h, R;

a = 3; b = 2; c = 4; d = 5; f = 8; g = 2; h = 6;

R = sub(mult(add(a, b), add(c, d)), add(div(f, g), h));

printf("\nThe Result of the Expression is : %d", R);

}

float div(int x, int y)

{

return((float)x / (float)y);

}

int mult(int x, int y)

{

return(x * y);

}

int add(int x, int y)

{

return(x + y);

}

int sub(int x, int y)

{

return(x - y);

}
