I'm attempting to create a power table in c using forloops, exponents, etc, but I'm new to c and haven't gotten particularly far on my own.
The code I've gotten to far is
#include <iostream>
#include <math.h>
#include <iomanip>
using namespace std;
int main() {
char again='y';
while (again == 'y'){
int power, rc, thing;
cout << "Please enter the power you wish to compute by. ";
cin >> power;
cout << "Please enter the maximum amount of rows and columns you would like to have. ";
cin >> rc;
int i=0;
while(i<=rc){
cout << setw(5) << i << " ";
i ;
}
for(int i=0; i<=rc; i ){
cout << setw(5) << i << " ";
thing = 1;
thing = pow(power, i);
cout << setw(5) << thing << endl;
}
cout << endl;
cout << "Enter 'y' to repeat action." << endl;
cin >> again;
}
}
Using 5 as both the power and number of rows and columns, the output so far is this. Which is where I now need help proceeding.
- How do I make it become a grid, going both horizontally and vertically until it's a full table?
- If it's just formatting, endl, and loops, how do I properly format it?
- How do I get rid of that annoying 0 1 on the top right of the table?
Any and all help would be appreciated at this point.
I'm trying to get the end result to look something like this: To the power of 4 and with 6 rows/columns,
1 2 3 4 5 6
1 | 1 16 81 256 625 1296
2 | 16 256 1296 4096 10000 20736
3 | 81 1296 6561 20736 50625 104976
4 | 256 4096 20736 65536 160000 331776
5 | 625 10000 50625 160000 390625 810000
6 | 1296 20736 104976 331776 810000 1.67962e 06
CodePudding user response:
You get rid of the 0 by replacing this:
int i=0;
while(i<=rc){
cout << setw(5) << i << " ";
i ;
}
with something that starts the counter at 1:
cout << " ";
for( int i = 1; i <= rc; i )
{
cout << setw(5) << i << " ";
}
cout << "\n";
You probably want to start the row counter at 1 as well, to get rid of the "0 1" line.
CodePudding user response:
To get rid of the 0 and 1 on the top you have to insert an endl
while(i<=rc){
cout << setw(5) << i << " ";
i ;
}
cout <<endl;
