C++ solutions :
//This is the program for show F :
Ques # 1
#include<iostream>
using namespace std;
int main()
{
float f = 5.00F; cout << f;

Q # 2:
for this patteren ://4 7 10 13 16...
#include<iostream>
using namespace std ;
int main()

//4 7 10 13 16 19 22.. also you can
int a=2;
for (a=2;a<=20;a++)
{

Ques # 3 :
for show the ans is 0
int i=4,j=1;
for(i=0;j>i;j--)
{
cout<<j-1<<endl;
}
return 0;
