Java
```java
public class Calculate1To100 {
public static void main(String[] args) {
int sum = 0;
for (int i = 1; i <= 100; i++) {
sum += i;
}
System.out.println("计算结果为: " + sum);
}
}
```
C语言
方法一:使用for循环
```c
include
int main() {
int sum = 0;
for (int i = 1; i <= 100; i++) {
sum += i;
}
printf("Sum of numbers from 1 to 100 is %d\n", sum);
return 0;
}
```
方法二:使用while循环
```c
include
int main() {
int sum = 0;
int i = 1;
while (i <= 100) {
sum += i;
i++;
}
printf("Sum of numbers from 1 to 100 is %d\n", sum);
return 0;
}
```
方法三:使用递归
```c
include
int function(int num) {
if (num < 100) {
num++;
return function(num);
}
return num;
}
int main() {
int sum = function(0);
printf("Sum of numbers from 1 to 100 is %d\n", sum);
return 0;
}
```
C++
```cpp
include
int main() {
int sum = 0;
for (int i = 1; i <= 100; i++) {
sum += i;
}
std::cout << "Sum of numbers from 1 to 100 is " << sum << std::endl;
return 0;
}
```
Python
```python
sum_of_numbers = sum(range(1, 101))
print("Sum of numbers from 1 to 100 is", sum_of_numbers)
```
JavaScript
```javascript
let sum_of_numbers = 0;
for (let i = 1; i <= 100; i++) {
sum_of_numbers += i;
}
console.log("Sum of numbers from 1 to 100 is", sum_of_numbers);
```
这些示例展示了如何使用不同的编程语言计算1到100的和。你可以选择最适合你的语言和环境的方法来实现这个任务。
