bootstrap 4 forms

To create Bootstrap 4 forms in C, you can use the appropriate HTML markup and CSS classes provided by Bootstrap. Here's an example of how you can create a basic form using Bootstrap 4:

#include <stdio.h>

int main() {
    printf("<form>\n");
    printf("  <div class=\"form-group\">\n");
    printf("    <label for=\"exampleInputName\">Name</label>\n");
    printf("    <input type=\"text\" class=\"form-control\" id=\"exampleInputName\" placeholder=\"Enter your name\">\n");
    printf("  </div>\n");
    printf("  <div class=\"form-group\">\n");
    printf("    <label for=\"exampleInputEmail\">Email</label>\n");
    printf("    <input type=\"email\" class=\"form-control\" id=\"exampleInputEmail\" placeholder=\"Enter your email\">\n");
    printf("  </div>\n");
    printf("  <button type=\"submit\" class=\"btn btn-primary\">Submit</button>\n");
    printf("</form>\n");

    return 0;
}

This code uses the form element to create a form and the form-group class to group form elements together. The label element is used to provide a label for each form field, and the input element is used to create input fields for users to enter their data. The form-control class is applied to the input fields to style them as Bootstrap form controls. Finally, the btn and btn-primary classes are used to create a submit button.

Please note that this code is for illustration purposes only and may need to be adapted to fit your specific needs.
