Creating various triangle patterns.
## Example
#includeusing namespace std; int main(){int rows; cout<>rows; for(int i = 1; i<= rows; ++i){for(int j = 1; j<= i; ++j){cout<<"* "; }cout<<"n"; }return 0; }
The output of the above program is:
** ** * ** * * ** * * * *
## Example
#includeusing namespace std; int main(){int rows; cout<>rows; for(int i = 1; i<= rows; ++i){for(int j = 1; j<= i; ++j){cout<<j<<""; }cout<<"n"; }return 0; }
The output of the above program is:
11 21 2 31 2 3 41 2 3 4 5
## Example
#includeusing namespace std; int main(){char input, alphabet = 'A'; cout<>input; for(int i = 1; i<= (input-'A'+1); ++i){for(int j = 1; j<= i; ++j){cout<<alphabet<<""; } ++alphabet; cout<<endl; }return 0; }
The output of the above program is:
A B B C C C D D D D E E E E E
## Example
#includeusing namespace std; int main(){int rows; cout<>rows; for(int i = rows; i>= 1; --i){for(int j = 1; j<= i; ++j){cout<<"* "; }cout<<endl; }return 0; }
The output of the above program is:
* * * * ** * * ** * * * **
## Example
#includeusing namespace std; int main(){int rows; cout<>rows; for(int i = rows; i>= 1; --i){for(int j = 1; j<= i; ++j){cout<<j<<""; }cout<<endl; }return 0; }
The output of the above program is:
1 2 3 4 51 2 3 4 1 2 31 21
## Example
#includeusing namespace std; int main(){int space, rows; cout<>rows; for(int i = 1, k = 0; i<= rows; ++i, k = 0){for(space = 1; space<= rows-i; ++space){cout<<""; }while(k != 2*i-1){cout<<"* "; ++k; }cout<<endl; }return 0; }
The output of the above program is:
* * * * * * * * * * * * * * * ** * * * * * * * *
## Example
#includeusing namespace std; int main(){int rows, count = 0, count1 = 0, k = 0; cout<>rows; for(int i = 1; i<= rows; ++i){for(int space = 1; space<= rows-i; ++space){cout<<""; ++count; }while(k != 2*i-1){if(count<= rows-1){cout<<i+k<<""; ++count; }else{ ++count1; cout<<i+k-2*count1<<""; } ++k; }count1 = count = k = 0; cout<<endl; }return 0; }
The output of the above program is:
1 2 3 2 3 4 5 4 3 4 5 6 7 6 5 45 6 7 8 9 8 7 6 5
## Example
#includeusing namespace std; int main(){int rows; cout<>rows; for(int i = rows; i>= 1; --i){for(int space = 0; space<rows-i; ++space)cout<<""; for(int j = i; j<= 2*i-1; ++j)cout<<"* "; for(int j = 0; j<i-1; ++j)cout<<"* "; cout<<endl; }return 0; }
The output of the above program is:
* * * * * * * * * * * * * * * * * * * * * * * * *
## Example
#includeusing namespace std; int main(){int rows, coef = 1; cout<>rows; for(int i = 0; i<rows; i++){for(int space = 1; space<= rows-i; space++)cout<<""; for(int j = 0; j<= i; j++){if(j == 0 || i == 0)coef = 1; else coef = coef*(i-j+1)/j; cout<<coef<<""; }cout<<endl; }return 0; }
The output of the above program is:
1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 1 5 10 10 5 1
## Example
#includeusing namespace std; int main(){int rows, number = 1; cout<>rows; for(int i = 1; i<= rows; i++){for(int j = 1; j<= i; ++j){cout<<number<<""; ++number; }cout<<endl; }return 0; }
The output of the above program is:
12 34 5 67 8 9 10
