11.C编程 - 生成乘法表

#include

int main()

{

int n, i;

printf("Enter an integer: ");

scanf("%d",&n);

for(i=1; i<=10; ++i)

{

printf("%d * %d = %d \n", n, i, n*i);

}

return 0;

}

12.C编程 - 斐波那契数列

#include

int main()

{

int i, n, t1 = 0, t2 = 1, nextTerm = 0;

printf("Enter the number of terms: ");

scanf("%d",&n);

// displays the first two terms which is always 0 and 1

printf("Fibonacci Series: %d, %d, ", t1, t2);

// i = 3 because the first two terms are already dislpayed

for (i=3; i <= n; ++i)

{

nextTerm = t1 + t2;

t1 = t2;

t2 = nextTerm;

printf("%d, ",nextTerm);

}

return 0;

}

13.C编程 - 数字为正或负

#include

int main()

{

double number;

printf("输入一个数字: ");

scanf("%lf", &number);

if (number <= 0.0)

{

if (number == 0.0)

printf("您输入了 0。");

else

printf("您输入了一个负数。都知道");

}

else

printf("你输入了一个正数。必须编程");

return 0;

}

14.C编程 - 在不使用库函数的示例情况下反转字符串

#include

#include

int main()

{

char str[100],rev[100];

int i,len=0;

printf("请输入字符串");

gets(str);

for(i=0;i<=100;i++)

{

if(str[i]==\0)

{

break;

}

len++;

}

for(i=0;i<=len-1;i++)

{

rev[i] = str[len-i-1];

}

printf("字符串的b2b信息网反向是 %s",rev);

return 0;

}

15.C编程 - 显示英文字母表

#include

int main()

{

char c;

for(c=A; c<=Z; ++c)

printf("%c ",c);

return 0;

}

16.C编程 - 回文串

#include

int main()

{

int n, reversedInteger = 0, remainder, originalInteger;

printf("Enter an integer: ");

scanf("%d", &n);

originalInteger = n;

// reversed integer is stored in variable

while( n!=0 )

{

remainder = n%10;

reversedInteger = reversedInteger*10 + remainder;

n /= 10;

}

// palindrome if orignalInteger and reversedInteger is equal

if(originalInteger == reversedInteger)

printf("%d is a palindrome.", originalInteger);

else

printf("%d is not a palindrome.", originalInteger);

return 0;

}

17.C编程 - 阿姆斯特朗编号

#include

int main()

{

int number, originalNumber, remainder, result = 0;

printf("Enter a three digit integer: ");

scanf("%d", &number);

originalNumber = number;

while (originalNumber != 0)

{

remainder = originalNumber%10;

result += remainder*remainder*remainder;

originalNumber /= 10;

}

if(result == number)

printf("%d is an Armstrong number.",number);

else

printf("%d is not an Armstrong number.",number);

return 0;

}

18.C编程 - 创建金字塔

#include

int main() {

int i, j;

int num;

printf("Enter the number of Digits :");

scanf("%d", &num);

for (i = 0; i <= num; i++) {

for (j = 0; j < i; j++) {

printf("%d ", i);

}

printf("\n");

}

return 0;

}

19.C编程 - 反转数字

#include

int main()

{

int n, reversedNumber = 0, remainder;

printf("Enter an integer: ");

scanf("%d", &n);

while(n != 0)

{

remainder = n%10;

reversedNumber = reversedNumber*10 + remainder;

n /= 10;

}

printf("Reversed Number = %d",reversedNumber);

return 0;

}

20.C编程 - 交换两个数字

#include

int main()

{

double firstNumber, secondNumber, temporaryVariable;

printf("Enter first number: ");

scanf("%lf", &firstNumber);

printf("Enter second number: ");

scanf("%lf",&secondNumber);

// Value of firstNumber is assigned to temporaryVariable

temporaryVariable = firstNumber;

// Value of secondNumber is assigned to firstNumber

firstNumber = secondNumber;

// Value of temporaryVariable (which contains the initial value of firstNumber) is assigned to secondNumber

secondNumber = temporaryVariable;

printf("\nAfter swapping, firstNumber = %.2lf\n", firstNumber);

printf("After swapping, secondNumber = %.2lf", secondNumber);

return 0;

}
