minx() max() Functions

int maxi(int *high_number, int size)

This function takes an array of integers high_number and its size size as input parameters. It returns the maximum value of the elements in the array.

int minx(int *smallest_num, int size)

This function takes an array of integers smallest_num and its size size as input parameters. It returns the minimum value of the elements in the array.

Usage

To use these functions, include the appropriate function definition in your code, and call the function with the appropriate arguments. For example:

int main() {
    int nums[] = {3, 7, 2, 8, 1, 5, 4, 9, 6};
    int size = sizeof(nums) / sizeof(int);

    int max = maxi(nums, size);
    int min = minx(nums, size);

    printf("The maximum value in the array is: %d\n", max);
    printf("The minimum value in the array is: %d\n", min);

    return 0;
}

This would set max_val to 9 and min_val to 1.

Rangex Function

This C function provides similar functionality to the rangex() built-in function in Python. Given a starting value, an ending value (exclusive), and a step size, it generates an array of integers containing the values in the range.

Function Signature

int* rangex(int start, int stop, int step, int* length);

Parameters

start: The starting value of the range.

stop : The ending value of the range (exclusive).

step : The step size between values in the range.

length : A pointer to an integer that will be set to the length of the resulting range.

Return Value

A pointer to an array of integers containing the values in the range.

example

int main() {
    int length;
    int* r = rangex(0, 1000, 5, &length);  
    int i;
    for (i = 0; i < length; i++) {
        printf("%d ", r[i]);
    }
    free(r);

    return 0;
}

Note that the implementation assumes that the input values are valid, so you may want to add additional error checking code to handle edge cases. Also, remember to free the memory allocated by the function using free() when you're done with it.

Sumx() Function in C

This is a simple example of a function in C that calculates the sum of an array of integers. The function sumx() takes a pointer to the first element of an array and the size of the array as parameters, and returns the sum of the elements in the array.

Function signature

The function signature is as follows:

int sumx(int *arr, int size);

where:

arr: pointer to the first element of an array of integers

size: size of the array

Example usage

Here is an example program that uses the sumx() function to calculate the sum of an array of integers:

#include <stdio.h>

int main() {
    int numbers[] = {1, 2, 3, 4, 5};
    int n = sizeof(numbers) / sizeof(numbers[0]);
    int total = sumx(numbers, n);
    printf("The sum is %d\n", total);
    return 0;
}

The program declares an array of integers numbers, and calculates its size using the sizeof operator. It then calls the sumx() function with the array and its size as arguments, and assigns the result to the variable total. Finally, it prints the total sum using printf().

lenx() Function

The lenx() function is a simple C function that returns the length of a given character array or string. It operates similar to the lenx() function in Python, which returns the number of items in a sequence.

Usage

The lenx() function can be called by passing a character array or string as its argument:

#include <stdio.h>

int main() {
    char str[] = "Hello, world!";
    int length = lenx(str);
    printf("Length of '%s' is %d\n", str, length);
    return 0;
}

This code will output:

Length of 'Hello, world!' is 13

The mapx() Function

The map() function is a built-in function in Python that applies a given function to each element of an iterable object (such as a list or tuple) and returns a new iterable object with the results.

In C programming language, there is no built-in mapx() function. However, you can define your own mapx() function using function pointers.

The mapx() function in the provided C code takes three arguments:

A function pointer fptr that takes an int and returns an int. This function will be applied to each element of the array.

An array of ints arr.

An integer size that specifies the size of the array.

The mapx() function returns a new array of ints with the result of applying the function fptr to each element of the input array arr.

Example

Here's an example of how to use the map() function in C:

int square(int n) {
    return n * n;
}

int main() {
    
    int numbers[] = {1, 2, 3};
    
    int size = sizeof(numbers) / sizeof(numbers[0]);
    
    int* squares = map(square,numbers,size);
    for (int i = 0; i < size; i++) {
        printf("%d ", squares[i]);
    }
    printf("\n");
    free(squares);
}

In this example, we define a square() function that calculates the square of an integer. We then create an array of integers and pass it to the map() function along with the square() function. The map() function applies the square() function to each element of the array and returns a new array with the results. We print the new array and free the memory allocated for it.

The output of the program should be:

1 4 9

This is the result of applying the square() function to each element of the numbers array.
