生活随笔收集整理的這篇文章主要介紹了多线程循环输出abcc++_C ++循环| 查找输出程序| 套装5 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

多線程循環輸出abcc++

Program 1:

程序1：

#include <iostream> using namespace std;int main() {int num = 15673;int R1 = 0, R2 = 0;do {R1 = num % 10;R2 = R2 * 10 + R1;num = num / 10;} while (num > 0);cout << R2 << " ";return 0; }

Output:

輸出：

37651

Explanation:

說明：

Here, we declared three local variables num, R1, and R2, and we are calculating the reverse of variable num, and R1 is used to extract the last digit in each iteration and R2 to store the result.

在這里，我們聲明了三個局部變量num ， R1和R2 ，并且正在計算變量num的倒數，并且R1用于提取每次迭代的最后一位， R2用于存儲結果。

Iteration 1: num=15673, R1=0, R2=0. After executing loop statements R1=3, R2=3, and num=1567.Iteration 2: num=1567, R1=3, R2=3. After executing loop statements R1=7, R2=37, and num=156.Iteration 3: num=156, R1=6, R2=37. After executing loop statements R1=6, R2=376, and num=15.Iteration 4: num=15, R1=5, R2=376. After executing loop statements R1=5, R2=3765, and num=1.Iteration 5: num=1, R1=1, R2=3765. After executing loop statements R1=1, R2=37651 and num=0.Then the condition will false and print "37651"

Program 2:

程式2：

#include <iostream> using namespace std;int main() {int I = 1;int D = 0;int R = 0;do {R = I++ * D++;cout << R << " ";} while (I <= 5);return 0; }

Output:

輸出：

0 2 6 12 20

Explanation:

說明：

In the above program, we declared three local variables I, D, and R.

在上面的程序中，我們聲明了三個局部變量I ， D和R。

Iteration 1: I=1, D=0, R=0 R = 1*0 R = 0 Then I=2 and D=1 and loop condition is true. Iteration 2: I=2, D=1, R=0 R = 2*1 R = 2 Then I=3 and D=2 and loop condition is true.Iteration 3: I=3, D=2, R=2 R = 3*2 R = 6 Then I=4 and D=3 and loop condition is true.Iteration 4: I=4, D=3, R=6 R = 4*3 R = 12 Then I=5 and D=4 and loop condition is true.Iteration 5: I=5, D=4, R=12 R = 5*4 R = 20 Then I=6 and D=5 and loop condition is false. And program terminates.

Program 3:

程式3：

#include <iostream> using namespace std;int main() {int I = 1;int D = 1;int R = 0;do {R = I++ * D++;if (I == 3)continue;cout << R << " ";} while (I <= 5);return 0; }

Output:

輸出：

1 9 16 25

Explanation:

說明：

In the above program, we declared three local variables I, D, and R.

在上面的程序中，我們聲明了三個局部變量I ， D和R。

Iteration 1: I=1, D=1, R=0 R = 1 * 1 R = 1 Print the value of R that is 1. Then I=2 and D=2 and loop condition is true. Iteration 2: I=2, D=2, R=1 R = 2 * 2 R = 4 But it will skip "cout" statement because of the continue statement. Then I=3 and D=3 and loop condition is true. Iteration 3: I=3, D=3, R=4 R = 3 * 3 R = 9 Print the value of R that is 9. Then I=4 and D=4 and loop condition is true. Iteration 4: I=4, D=4, R=9 R = 4 * 4 R = 16 Print the value of R that is 16. Then I=5 and D=5 and loop condition is true. Iteration 5: I=5, D=5, R=16 R = 5 * 5 R = 25Print the value of R that is 25. Then I=6 and D=6 and loop condition is false. Then the loop will terminate.
