Status function bar - C

Question

I have this function:

void choiceTwo(void){

    system("clear");
    printf("================ RUN ALL FUNCTION ================\n\n");

    printf("\nTest case 'create/destroy'... ");
    fflush(stdout);
    test_create_destroy();
    printf("OK\n");

    printf("Test case 'add/remove edge'... ");
    fflush(stdout);
    test_add_remove_edge();
    printf("OK\n");

    printf("Test case 'print graph'... ");
    fflush(stdout);
    test_print_graph();
    printf("OK\n");

    printf("Test case 'null'... ");
    fflush(stdout);
    test_null();
    printf("OK\n");

    printf("\nPress enter to continue ");
    getchar();
    getchar();
    main();
}

How can I print the status of this function by using a progress bar (in percent) like this in the picture?

Status Bar

I tried to do this using python, but do not know how to fully control the function status

try this code

#include <stdio.h>
#include <unistd.h>

void working ( int showat, int done, int total) {
    char dash[51]  = "--------------------------------------------------";
    char blank[51] = "                                                  ";
    int portion = 0;
    float percent = 0.0f;

    printf ( "\033[?25l");//hide cursor
    printf ( "\033[38;5;10m");//green text
    printf ( "\033[48;5;0m");//on black
    printf ( "\033[%d;H", showat);//move curson to line showat
    percent = ( (float)done * 100) / total;
    portion = percent / 2.0f;
    printf ( "Progress: [\033[38;5;0m\033[48;5;10m");//black text on green
    printf ( "%.*s\033[38;5;10m\033[48;5;0m%.*s]%6.1f%% Complete\r"//back to green text on black
    , portion, blank, 50 - portion, dash, percent);

    printf ( "\033[0m");//reset color
    printf ( "\033[?25h");//show cursor
}

void test_progress ( ) {
    int item = 0;
    int allitems = 200;
    //do things in functioin where you need to show progress
    for ( item = 0; item <= allitems; item++) {
        working ( 5, item, allitems);
        usleep ( 50000);
    }
}

void test_loop ( ) {
    int item = 0;
    int allitems = 500;
    //do things in functioin where you need to show progress
    for ( item = 0; item <= allitems; item++) {
        working ( 9, item, allitems);
        usleep ( 50000);
    }
}

void choiceTwo(void){

    printf ( "\033[2J");//clear screen
    printf ( "\033[0;H");//move curson to line 0
    printf("================ RUN PROGRESS TEST ================\n\n");

    printf("\nTest progress'... ");
    test_progress();
    printf("\nOK\n");


    printf("\nTest loop'... ");
    test_loop();
    printf("\nOK\n");

}

int main()
{
    choiceTwo ( );
    return 0;
}
