Question

what is setw( ) and setprecision () and how do i use them?

Answer 1

setw() under iomanip use to make space by simply writing the value inside the parentheses
setpreecision=it set a number of digits after a comma (it is also under iomanip)

Answer 2

here is my code : #include <iostream>
#include <string>
#include <iomanip>
using namespace std;

int main()
{

float a= 3.0, b= 5.0, c = 7.1, d=8.3, e=2.2, f=3.2 , g= 6.1, product ;
int h=5 ;

cout << " " << setprecision(2) << a << endl;
cout << "*" << setprecision(2) << b << endl;

cout << "----------" << endl;


product = a*b ;

cout << product << endl;

system ("pause") ;
}

Answer 3

however the setprecision is not working

Answer 4

#include <iostream>
#include <string>
#include<iomanip>
using namespace std;

int main()
{
float product ;//your type must b type float
float a= 3.0, b= 5.0, c = 7.1, d=8.3, e=2.2, f=3.2 , g= 6.1;
int h=5 ;//wat is the use of c,d,e,f,g,h

cout << " " << a <<endl;
cout<< "* "<<b<<endl;


cout << "-------------" << endl;

cout<<setprecision(2) <<fixed;
product = 3.0*5.0 ;
cout << product << endl;





system ("pause") ;
}
