這些都是基本的 C 程序，可以幫助剛踏入 C 編程世界的新手?？靵碓囋嚢桑?/p>

1、C 語言編程 – Hello World

#includeint main(){    printf("Hello world
");    printf("Linux迷 www.linuxmi.com");    return 0;}

2. C 語言編程 - 執(zhí)行算術(shù)運(yùn)算

#includeint main(){int a,b;printf("Enter two numbers:");scanf("%d%d",&a,&b);printf("Sum=%d difference=%d product=%d quotient=%d
",a+b,a-b,a*b,a/b);return 0;}

3.C 編程 - 求圓的面積

#include#includeint main(){    float r;    float N=3.14;    float s;    //N*r*r;該行必須在輸入r值以后    printf("請輸入該圓的半徑:");    scanf("%f",&r);        s=N*r*r;    printf("%.7f
",s);//輸出小數(shù)點(diǎn)后7位    return 0;}

4.C編程 - 在3個數(shù)字中找到最大值

#includeint main()  {int a, b, c;printf("
Enter value of a, b & c : ");scanf("%d %d %d", &a, &b, &c);if ((a > b) && (a > c))printf("
a is greatest
");if ((b > c) && (b > a))printf("
b is greatest
");if ((c > a) && (c > b))printf("
c is greatest
");return 0;}

5.C編程 - 查找偶數(shù)或奇數(shù)

#includeint main(){int n;printf("Enter a number:");scanf("%d",&n);if(n%2==0){printf("Number is even
");}else{printf("Number is odd
");}return 0;}

6. C編程 - 顯示一個數(shù)字的因數(shù)

#include 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編程 - 檢查質(zhì)數(shù)

#include 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);elseprintf("%d is not a prime number.
",n);return 0;}

8.C編程 - 檢查閏年

#includeint 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.
", year);elseprintf("%d is not a leap year.
", year);}elseprintf("%d is a leap year.
", year );}elseprintf("%d is not a leap year.
", year);return 0;}

9.C編程 - 從1加到n的和

#includeint 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
",sum);return 0;}

10. C編程 - 一個數(shù)的階乘

#include 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, factorial);}return 0;}

這些 C 編程示例，可以很好的幫助初學(xué)者進(jìn)行編碼之旅。
