Here, we will see how to print a triangle using the C program
Input:
5
Output:
* * * * * * * * * * * * * * *
Approach:
The approach is very simple. We just execute a nested loop, and only print characters when the inner loop is executed after that just change the line.
Example:
C
// C program to print a triangle #include <stdio.h> // Driver code int main()
{ int n = 6;
// ith row has i elements
for ( int i = 1; i <= n; i++) {
for ( int j = 1; j <= i; j++) {
printf ( "*" );
}
printf ( "\n" );
}
return 0;
} |
Output
* ** *** **** ***** ******
Time Complexity: O(n2)
Auxiliary Space: O(1), No extra Space is used.
