Java
```java
public class SumOfNumbers {
public static void main(String[] args) {
int sum = 0;
for (int i = 1; i <= 100; i++) {
sum += i;
}
System.out.println("Sum of numbers from 1 to 100 is " + sum);
}
}
```
C语言
```c
include
int main() {
int i, sum = 0;
for (i = 1; i <= 100; i++) {
sum += i;
}
printf("Sum of numbers from 1 to 100 is %d\n", sum);
return 0;
}
```
Python
```python
sum_of_numbers = sum(range(1, 101))
print("Sum of numbers from 1 to 100 is", sum_of_numbers)
```
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;
}
```
JavaScript
```javascript
let sum = 0;
for (let i = 1; i <= 100; i++) {
sum += i;
}
console.log("Sum of numbers from 1 to 100 is " + sum);
```
这些代码示例分别使用Java、C语言、Python、C++和JavaScript编程语言实现了1到100所有整数求和的功能。你可以选择适合你的编程语言进行学习和使用。
