Conditional Rendering in React Complete Guide with Examples 2026

Image
  Conditional Rendering in React Conditional Rendering is one of the most useful concepts in React. It means showing different content on the screen depending on a condition. For example: If a user is logged in → show Logout If a user is not logged in → show Login If a student has passed → show Congratulations If a product is available → show Buy Now If data is loading → show Loading... React does not have a separate if rendering tag. Instead, we use normal JavaScript conditions such as if, the ternary operator, &&, and switch to decide what should appear in the UI.

    for (a = 0; a < n; a++)
{
        for (b = 0; b < n;b++)
{
            if (b == 0 || b == n - 1 || a == n / 2)

C Program to Print Alphabet H Star Pattern with Example
Explain Program

Step :1

#include <stdio.h>

  • standard input-output library use functions like printf().

Step :2

int main()

  • The entry point of any C program.
Returns an integer 

Step :3

int a, b;

  • These are loop variables used in the nested for loops:
  • a: Controls the rows.
  • b: Controls the columns.

Step :4

int n = 7;

  • n is the dimension of the pattern.
  • The output will be a 7x7 grid 
  • You can modify n to change.

Step :5

for (a = 0; a < n; a++)

  • Outer loop — iterates over rows from 0 to 6 (7 iterations).

Step :6

for (b = 0; b < n; b++)

  • Inner loop — iterates over column from 0 to 6.
Step :7

if (b == 0 || b == n - 1 || a == n / 2)

key condition to print the star *:

  • b == 0 → First column (left vertical line)
  • b == n - 1 → Last column (right vertical line)
  • a == n / 2 → Middle row (horizontal bar)

Step :8

printf("*");

 printf(" ");

  • Prints either a star or a space.

Step :9

printf("\n");

  • After each row is complete, this move to the next line.

Step :10

return 0;
