area of cicle ,reactangle .cylinder using swich statments

ReplyDeleteto generate the first n terms in the series --- 6,11,21,36,56,...

ReplyDeletea = 1;

Deleteb = 5

for (i=1; i<=n; i++)

{

printf("%d ",a+b);

b = b+5;

}

5 cannot be assumed it must got as input sir and btw wrong answer

Deletethen take input of x, start b = x and the b = b + x
