C++ Triangle making. - Wayn - 05.10.2012

so i decided to make a code where i can make a TRIANGLE using only one "*" (staric character) for loops.i dont want to simply print multiple sterrics by myself. so please tell me what is wrong with my code?

Код:

#include <iostream>

using namespace std;

int main()
{
    int i,j;
    for(i=1;i<=6;++i)
    {
      for(j=1;j<=6;++j)
      cout<<"*";
      cout<<endl;

    }
    return 0;
}

The result should be like this:
*

Код:

#define TRIANGE_SIZE 6
int main() {
    int start = 1;
    while(start != TRIANGLE_SIZE) {
        for(new i=0; i<start; i++) {
            cout<<"*";
            cout<<endl;
        }
        start++;
    }
}

You should make your homework yourself though.

Код:

#define TRIANGLE_SIZE 6
using namespace std;

int main() {
    int start = 1;
    while(start != TRIANGLE_SIZE) {
        for(int i=0; i<start; i++) {
            cout<<"*";
            cout<<endl;
        }
        start++;
    }
}

used this, changed the 'new' to 'int' but no luck
this is my output using this:

@Wayn: Try this ...

Код:

#include <iostream>
using namespace std;

#define SIZE    10

int main()
{
    int i,j;
    
    for(i=1; i<=SIZE; ++i) {
        for(j=1; j<=i; ++j) cout<<"*";
        cout<<endl;
    }
    
    system("pause");
    return 0;
}

Output:

Код:

*

i - represent the line nr [from 1 to SIZE]
j - how many "*" whill show [from 1 to i (the nr of "*" ar the same whit the line nr) ]

    int start = 1;
    while(start != TRIANGLE_SIZE) {

        for(int i=0; i<=start; i++) { //will show "TRIANGLE_SIZE" lines whit "*"
            cout<<"*";
            //cout<<endl;

        cout<<endl; //this is the place where shud be

Thanks man ! rep for you ^^

Re: C++ Triangle making. - Mr.Anonymous - 05.10.2012

I'm sorry to reply here, but what program do you use to code in C++? I know Turbo C++ though.

Re: C++ Triangle making. - TheArcher - 05.10.2012

My school uses DevC++ for that shits

Re: C++ Triangle making. - Jessyy - 06.10.2012

I'm using the same program like @TheArcher ... Dev-C++ http://www.bloodshed.net/devcpp.html
