Convert this to c def foo(x): sum = 0 for i in range(x): x += i sum += x return sum

Output

To convert the given Python function to C, we need to account for the fact that the loop in the original code runs a fixed number of times based on the initial value of `x`, even though `x` is modified within the loop. Here's the equivalent C code:

int foo(int x) {
    int sum = 0;
    int original_x = x; // Store the initial value of x
    for (int i = 0; i < original_x; i++) {
        x += i;
        sum += x;
    }
    return sum;
}
**Explanation:** 1. **Capture Initial `x`:** The variable `original_x` holds the initial value of `x` to ensure the loop runs exactly `original_x` times, mirroring Python's `range(x)` behavior which is evaluated once at the start. 2. **Loop Control:** The loop iterates from `i = 0` to `i < original_x`, ensuring the correct number of iterations even if `x` is modified inside the loop. 3. **Modify `x` and Update `sum`:** Within each iteration, `x` is incremented by `i`, and the updated `x` is added to `sum`, replicating the Python logic. This approach accurately replicates the behavior of the original Python function in C.

#include<stdio.h>

int main() {


int answer = foo(10);
int expected = 265;
if (answer != expected) {
    printf("Wrong answer; got %d instead of %d.\n", answer, expected);
    exit(1);
}
printf("All tests passed\n");
}
And got the output: All tests passed
