Question No:02:

Question No: 02 Algorithm:

→Start →Read x

→Read y

→Read r

→r=x/y

→If (y==0)

→Not possible

→else

→Display quotient

→End

Question No:02 Flow Chart:

→Average= (obtained marks/total marks)*

→Final marks of class = final marks of class + obtained marks of class

→Overall average of whole class = (final marks of class / total marks of class)*

→Display Overall Average of class

→End

Question No:05 Program code:

#include using namespace std; int main() { int y; /me assume 'y' as number of years/ float ia, r, f = 0; /me assume 'ia' as initial amount, 'r' as Rate of Interest, 'f' as balance at the end of years/

cout << "\n Enter the Initial Amount:"; cin >> ia; cout << "\nEnter the number of years:"; cin >> y; cout << "\nEnter the rate of interest (percent per year):"; cin >> r; r = r / 100; /* use this formula to convert rate of interest form point(.) into number*/ f = ia;
