言语治疗技术习题(言语治疗技术试题)

这些都是基本的 C 程序，可以帮助刚踏入 C 编程世界的新手。快来试试吧：

1、C 语言编程 – Hello World

#include<stdio.h>int main(){ printf("Hello world\n"); printf("Linux迷 www.linuxmi.com"); return 0;}

2. C 语言编程 - 执行算术运算

#include<stdio.h>int main(){int a,b;printf("Enter two numbers:");scanf("%d%d",&a,&b);printf("Sum=%d difference=%d product=%d quotient=%d\n",a+b,a-b,a*b,a/b);return 0;}

3.C 编程 - 求圆的面积

#include<stdio.h>#include<math.h>int main(){ float r; float N=3.14; float s; //N*r*r;该行必须在输入r值以后 printf("请输入该圆的半径:"); scanf("%f",&r); s=N*r*r; printf("%.7f\n",s);//输出小数点后7位 return 0;}

4.C编程 - 在3个数字中找到最大值

#include<stdio.h>int main() {int a, b, c;printf("\nEnter value of a, b & c : ");scanf("%d %d %d", &a, &b, &c);if ((a > b) && (a > c))printf("\na is greatest\n");if ((b > c) && (b > a))printf("\nb is greatest\n");if ((c > a) && (c > b))printf("\nc is greatest\n");return 0;}

5.C编程 - 查找偶数或奇数

#include<stdio.h>int main(){int n;printf("Enter a number:");scanf("%d",&n);if(n%2==0){printf("Number is even\n");}else{printf("Number is odd\n");}return 0;}

6. C编程 - 显示一个数字的因数

#include <stdio.h>int main(){int n,i;printf("Enter a positive integer: ");scanf("%d",&n);printf("Factors of %d are: ", n);for(i=1;i<=n;++i){if(n%i==0)printf("%d ",i);} return 0;}

7. C编程 - 检查质数

#include <stdio.h>int main(){int n, i, flag = 0;printf("Enter a positive integer: ");scanf("%d",&n);for(i=2; i<=n/2; ++i){// condition for nonprime numberif(n%i==0){flag=1;break;}}if (flag==0)printf("%d is a prime number.\n",n);elseprintf("%d is not a prime number.\n",n);return 0;}

8.C编程 - 检查闰年

#include<stdio.h>int main(){int year;printf("Enter a year: ");scanf("%d",&year);if(year%4 == 0){if( year%100 == 0){// year is divisible by 400, hence the year is a leap yearif ( year%400 == 0)printf("%d is a leap year.\n", year);elseprintf("%d is not a leap year.\n", year);}elseprintf("%d is a leap year.\n", year );}elseprintf("%d is not a leap year.\n", year);return 0;}

9.C编程 - 从1加到n的和

#include<stdio.h>int main(){int i,n,sum=0;printf("Upto how many terms you want to find the sum:");scanf("%d",&n);for(i=1;i<=n;i++){sum = sum + i;}printf("Sum is %d\n",sum);return 0;}

10. C编程 - 一个数的阶乘

#include <stdio.h>int main(){int n, i;unsigned long long factorial = 1;printf("Enter an integer: ");scanf("%d",&n);// show error if the user enters a negative integerif (n < 0)printf("Error! Factorial of a negative number doesn't exist.");else{for(i=1; i<=n; ++i){factorial *= i; // factorial = factorial*i;}printf("Factorial of %d = %llu\n", n, factorial);}return 0;}

这些 C 编程示例，可以很好的帮助初学者进行编码之旅。
