for loop: A Multiplication Table
#include<iostream>
using namespace std;
int main(void)
{
cout << "A multiplication table:" << endl
<< " 1\t2\t3\t4\t5\t6\t7\t8\t9" << endl
<< "" << endl;
for(int c = 1; c < 10; c++)
{
cout << c << "| ";
for(int i = 1; i < 10; i++)
{
cout << i * c << "\t";
}
cout << endl;
}
return 0;
}
For loop with int value type as the control
#include <iostream>
using namespace std;
int main()
{
int b, e, r;
cout << "Enter base: ";
cin >> b;
cout << "Enter exponent: ";
cin >> e;
r = 1;
for( ; e; e--)
r = r * b;
cout << "Result: " << r;
return 0;
}
For statement
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
double rate = 1.15;
cout << fixed << setprecision(2);
cout << "Euro Dollar\n";
for( int euro = 1; euro <= 5; ++euro)
cout << " " << euro
<< " " << euro*rate << endl;
return 0;
}
