#include <stdio.h>
int main() {
int num, i;
printf("Enter a positive integer: ");
scanf("%d", &num);
printf("Factors of %d are: ", num);
for (i = 1; i <= num; ++i) {
if (num % i == 0) {
printf("%d ", i);

write a c program that reads a positive
integer n from the user and calculates the sum of all the positive integers from 1 to n.
#include <stdio.h>
int main() {
int n, sum = 0;
printf("Enter a positive integer: ");
scanf("%d", &n);
for (int i = 1; i <= n; i++) {
sum += i;
}
printf("The sum of all positive integers from 1 to %d is %d\n", n, sum);
return 0;
}
Write a program that reads an expression in a line as input and prints out the result. Only integers and operators below are allowed in the expression:
Sure, I can help you with that! Here is a Python code snippet that can evaluate simple arithmetic expressions containing only integers and the operators +, -, *, and /:
```python
expression = input("Enter an arithmetic expression: ")
result = eval(expression)
print("Result:", result)
```
You can copy and paste this code into a Python IDE or a Jupyter notebook and execute it. When prompted, enter an arithmetic expression like "2+3*4" and press Enter. The program will then evaluate the expression and print out the result, which in this case should be 14.
Note that the `eval()` function is used to evaluate the expression entered by the user as a Python expression. This means that the user can potentially enter any valid Python expression, so you should be careful when using this function in a production environment.
