C program to print pattern of Floyd's triangle
A for loop
is a repetition control structure that allows you to efficiently write a loop
that needs to execute a specific number of times.
Syntax
The syntax of a for loop
in C programming language is −
for(init; condition; increment){
statement(s);
}
Here is the flow of control in a 'for' loop −
- The init step is executed first, and only once. This step allows you to declare and initialize any loop control variables. You are not required to put a statement here, as long as a semicolon appears.
- Next, the condition is evaluated. If it is true, the body of the loop is executed. If it is false, the body of the loop does not execute and the flow of control jumps to the next statement just after the 'for' loop.
- After the body of the 'for' loop executes, the flow of control jumps back up to the increment statement. This statement allows you to update any loop control variables. This statement can be left blank, as long as a semicolon appears after the condition.
The condition is now
evaluated again. If it is true, the loop executes and the process repeats
itself (body of loop, then increment step, and then again condition). After the
condition becomes false, the 'for' loop terminates
#include <stdio.h>int main(){int rows, i, j, number= 1;printf("Enter number of rows: ");scanf("%d",&rows);for(i=1; i <= rows; i++){for(j=1; j <= i; ++j){printf("%d ", number);++number;}printf("\n");}return 0;}
