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.

{

int row,i,j,number=1;
clrscr();
printf("enter the number");
scanf("%D",&row);
for(i=1;i<=row;i++)

C Program to Display Floyd’s Triangle Pyramid Pattern

Explain Program

Step :1

#include <stdio.h>

  • Standards Input/Output Library.
  •  using printf() and scanf().

Step :2

int main()

  •  entry point of the program.
Step :3

int row, i, j, number = 1;

Declares variables:-
  • row :- User input for number of rows in Floyd's Triangle.
  • i :- Loop variable for rows.
  • j :- Loop variable for elements in each row.
  • number :- Holds the current number to print; starts at 1.

Step :4

printf("Enter the number of row ");

  •  input how many rows they want in the triangle.

Step :5

scanf("%d", &row);

  •  user input and stores  variable row.
  • format specifier for integers.

Step :6

for(i = 1; i <= row; i++)

  •  number of rows in the triangle.
  • Runs from 1 to row 

Step :7

for(j = 1; j <= i; j++)

  • Control  the number of element  row.
  • Each row i contains exactly i numbers.

Step :8

printf("%d ", number);

  • Prints a space.

Step :9

printf("\n");

  • next line after each row is printed

Step :10

return 0;

successful termination of the program
