Example: Factorial Using for Loop The following code uses aforloop to calculate the factorial value of a number. Note that the factorial of a number is the product of all integers between 1 and the given number. The factorial is mathematically represented by the following formula − ...
Let’s look at the “for loop” from the example: We first start by setting the variable i to 0. This is where we start to count. Then we say that the for loop must run if the counter i is smaller then ten. Last we say that every cycle i must be increased by one (i++). ...
for(count=1;count<=n;++count) /* for loop terminates if count>n */ { factorial*=count; /* factorial=factorial*count */ } printf("Factorial = %lu",factorial); } return 0; } 输出1: Enter an integer: -5 Error!!! Factorial of negative number doesn't exist. 输出2 Enter an integer...
Looping is the process by which you can give instruction to the compiler to execute a code segment repeatedly, here you will find programs related to c looping – programs using for, while and do while. Here you will get nested looping (loop within loop) programs....
这是无限for循环的另一个例子: // infinite loopfor( ; ; ) {// statement(s)} 示例:使用for循环显示数组元素 #include<iostream>usingnamespacestd;intmain(){intarr[]={21,9,56,99,202};/* We have set the value of variable i * to 0 as the array index starts with 0 ...
