C program calculates the square roots of five numbers. The variable count stores the count of numbers read. When count is less than or equal to 5, the goto read statement will control the label pointed to the read. Otherwise, the program prints a message and stops.
Goto statement
It is used after the normal program execution sequence to transfer control to other parts of the program.
Program
The following is a C program using goto statement-
#include <math.h> main(){ double x, y; int count; count = 1; printf("Enter FIVE real values in a LINE </p><p>"); read: scanf("%lf", &x); printf("</p><p>"); if (x < 0) printf("Value - %d is negative</p><p>",count); else{ y = sqrt(x); printf("%lf\t %lf</p><p>", x, y); } count = count + 1; if (count <= 5) goto read; printf("</p><p>End of computation"); }
Output
When executed When executing the above program, the following results will be produced -
Enter FIVE real values in a LINE 2.3 -4.5 2 6.8 -44.7 2.300000 1.516575 Value - 2 is negative 2.000000 1.414214 6.800000 2.607681 Value - 5 is negative End of computation

VScode中怎么配置C语言环境?下面本篇文章给大家介绍一下VScode配置C语言环境的方法(超详细),希望对大家有所帮助!

在C语言中,node是用于定义链表结点的名称,通常在数据结构中用作结点的类型名,语法为“struct Node{...};”;结构和类在定义出名称以后,直接用该名称就可以定义对象,C语言中还存在“Node * a”和“Node* &a”。

c语言将数字转换成字符串的方法:1、ascii码操作,在原数字的基础上加“0x30”,语法“数字+0x30”,会存储数字对应的字符ascii码;2、使用itoa(),可以把整型数转换成字符串,语法“itoa(number1,string,数字);”;3、使用sprintf(),可以能够根据指定的需求,格式化内容,存储至指针指向的字符串。

在c语言中,没有开根号运算符,开根号使用的是内置函数“sqrt()”,使用语法“sqrt(数值x)”;例如“sqrt(4)”,就是对4进行平方根运算,结果为2。sqrt()是c语言内置的开根号运算函数,其运算结果是函数变量的算术平方根;该函数既不能运算负数值,也不能输出虚数结果。

C语言数组初始化的三种方式:1、在定义时直接赋值,语法“数据类型 arrayName[index] = {值};”;2、利用for循环初始化,语法“for (int i=0;i<3;i++) {arr[i] = i;}”;3、使用memset()函数初始化,语法“memset(arr, 0, sizeof(int) * 3)”。

c语言合法标识符的要求是:1、标识符只能由字母(A~Z, a~z)、数字(0~9)和下划线(_)组成;2、第一个字符必须是字母或下划线,不能是数字;3、标识符中的大小写字母是有区别的,代表不同含义;4、标识符不能是关键字。

c语言编译后生成“.OBJ”的二进制文件(目标文件)。在C语言中,源程序(.c文件)经过编译程序编译之后,会生成一个后缀为“.OBJ”的二进制文件(称为目标文件);最后还要由称为“连接程序”(Link)的软件,把此“.OBJ”文件与c语言提供的各种库函数连接在一起,生成一个后缀“.EXE”的可执行文件。

c语言计算n的阶乘的方法:1、通过for循环计算阶乘,代码如“for (i = 1; i <= n; i++){fact *= i;}”;2、通过while循环计算阶乘,代码如“while (i <= n){fact *= i;i++;}”;3、通过递归方式计算阶乘,代码如“ int Fact(int n){int res = n;if (n > 1)res...”。
