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

Output

Below is one way to convert the Python code to C. One important note is that Python’s range(x) calculates the sequence based on the original value of x before entering the loop. In C, if we use x in the loop condition and then modify it inside the loop, it would change behavior. To preserve the original loop count, we save the initial value of x in another variable (here, we use n). Here’s the equivalent C code: ----------------------------------------------------- #include <stdio.h> int foo(int x) { int sum = 0; int n = x; // Save the original value of x for the loop count. for (int i = 0; i < n; i++) { x += i; sum += x; } return sum; } int main(void) { int result = foo(5); // Example call to foo with x = 5 printf("Result: %d\n", result); return 0; } ----------------------------------------------------- Explanation: 1. The function foo takes an integer x as an argument. 2. We declare an integer n to store the original value of x. This ensures the loop runs exactly n times (as in Python’s range(x)). 3. Inside the loop, we modify x by adding i, and then add the updated x to sum. 4. Finally, foo returns the computed sum. 5. The main function shows an example of calling foo and printing its result. This code should compile and run as expected.

Output

Below is one way to convert the given Python code to C. Note that in Python, the expression range(x) is evaluated once at the start (using the initial value of x). In C, if you simply use x in the loop condition (i.e. for (i = 0; i < x; i++)), then modifying x inside the loop would affect the loop condition. To mimic Python’s behavior exactly, we first store the original x value in another variable (here called n) and then iterate from 0 to n – 1. The following C code should behave the same as the Python code: ------------------------------------------------- #include <stdio.h> int foo(int x) { int sum = 0; int n = x; // Save the original value of x for loop iterations for (int i = 0; i < n; i++) { x += i; sum += x; } return sum; } int main(void) { int value = 5; // example input int result = foo(value); printf("foo(%d) = %d\n", value, result); return 0; } ------------------------------------------------- Explanation: 1. The function foo takes an integer x. 2. We store the initial x in n to ensure the loop iterates the correct number of times. 3. For each iteration from i = 0 to n - 1, we update x by adding i and then add the new x to the running sum. 4. Finally, the function returns the computed sum. Compile and run this code with a C compiler to verify its correctness.
