In the above example we have a for loop inside another for loop, this is called nesting of loops. One of the example where we use nested for loop isTwo dimensional array. Multiple initialization inside for Loop in C We can have multiple initialization in the for loop as shown below. for...
Syntax and Examples of For Loop in C Programming The essential syntax of a for loop in C is: for ( ; ; ) This for loop lacks an evaluation expression. If nothing is evaluated as true or false, there can be no exit to this loop. If this program ran, it would begin an infinite ...
1) for loop as an infinite loop to hold execution When, we need to hold execution of program (or hang the program), we can use thefor loop as an infinite loop. for(;1;); Consider the program: #include<stdio.h>#include<stdlib.h>intmain(){printf("start...\n");fflush(stdout);fo...
for(inti =0; i <5; i++) { cout << i <<"\n"; } Try it Yourself » Example explained Statement 1 sets a variable before the loop starts:int i = 0 Statement 2 defines the condition for the loop to run:i < 5. If the condition is true, the loop will start over again, if...
Here is a basic C program covering usage of ‘do-while’ loop in several cases: #include <stdio.h> int main () { int i = 0; int loop_count = 5; printf("Case1:\n"); do { printf("%d\n",i); i++; } while (i<loop_count); ...
C for 循环 C 循环for 循环允许您编写一个执行指定次数的循环控制结构。语法C 语言中 for 循环的语法:for ( init; condition; increment ) { statement(s); }下面是 for 循环的控制流:init 会首先被执行,且只会执行一次。这一步允许您声明并初始化任何循环控制变量。您也可以不在这里写任何语句,只要有一个...
