Final Answer

if you want to use same block of code repeatedly then we use function

function reduce the effort write same code repeatedly. we can just call the function work is done.

for example

int sum( int a , int b ) // It is called function definition 

{ int result ;

result = a + b ;

return result;


int main ( void )


int sum1 = sum(10,20); // function call

int sum2 = sum(20,20);

int sum3 = sum(30,30);

printf("%d",sum1); // 30

printf("%d",sum2); // 40

printf("%d",sum3); // 60
