for(int i = 0; i < 5; i++) { | OUTPUT 2 for(int j=0;j<=i;j++){ 3 printf("* "); 4 } 5 printf("\n"); 6}

This code is a nested for loop in C that prints a right-angled triangle made of asterisks (*). Here's a breakdown of what it does:

Code Analysis:

for(int i = 0; i < 5; i++) {
    for(int j = 0; j <= i; j++) {
        printf("* ");
    }
    printf("\n");
}

How it works:

  1. Outer Loop (i):

    • The outer for loop runs 5 times (from i = 0 to i = 4).
    • i represents the current row being printed.
  2. Inner Loop (j):

    • For each iteration of the outer loop, the inner for loop runs (i + 1) times (j going from 0 to i).
    • In each iteration of the inner loop, the code prints * (an asterisk followed by a space).
  3. Newline:

    • At the end of each iteration of the outer loop (i.e., after completing the inner loop), a newline (\n) is printed to move to the next row.

Output:

The output is a right-angled triangle of asterisks (*), where the number of asterisks in each row corresponds to the row number (starting from 1). It looks like this:

* 
* * 
* * * 
* * * * 
* * * * * 

Summary:

The code uses nested loops to print a right-angled triangle of asterisks. Each row contains one more asterisk than the previous row, starting from 1 asterisk in the first row.
