tables...

This is a discussion on tables... within the C Programming forums, part of the General Programming Boards category; seperate your printf statement into 2 printf statements.. seperate them just after where you see the first \n. use this ...

    seperate your printf statement into 2 printf statements.. seperate them just after where you see the first \n. use this first statement to print the table 'headers' and 'footers', ie:

    printf("case\t....");

    for loop

    printf("case\t...");

    the equations arent programming specific, and they are related to your field, and also on the assignment website. declare some variables and give it a shot , post back your for loop.

    my new problem...

    Code:
        fputs("case\t"  "voltage\t"  "Initial Resistance\t"  "Ending resistance\t"  "Increment Resistance\n", stdout);
    
        printf("%lf\t"  "%lf\t"      "%lf\t"                 "%lf\t"                "%lf\n", volts, init, ending, increment);
    
    
    return 0;
    
    }
    I have no way to line these up... depending on the size of the variables the tabs need to be altered.... is their another way?

    p.s. i'll go work on making a loop.

    in place of using tabs (which don't always show up as tabs), use "%-10lf" for left-aligned 10 character output (with padded spaces).

    You now know that there are exactly 10 outputed chars.

    i think i made it worse...
    Code:
    #include <stdio.h>
    #include <math.h>
    int main(void)
    
    {
    
    
        double volts, init, ending, increment, part=1;
        fputs("What is the voltage?", stdout);
          scanf("%lf", &volts);
        fputs("What is the initial resistance?", stdout);
          scanf("%lf", &init);
        fputs("What is the ending resistance?", stdout);
          scanf("%lf", &ending);
        fputs("What is the increment resistance?", stdout);
          scanf("%lf", &increment);
    
        fputs("case\t"  "voltage\t"  "Initial Resistance\t"  "Ending resistance\t"  "Increment Resistance\n", stdout);
    
        printf("lf"  "%-10lf"      "%-10lf"                 "%-10lf"                "%-10lf\n", part, volts, init, ending, increment);
    
        fputs("would you like to run the program again?", stdout);
        char r, y;  scanf("%i, &r");
    
    
        scanf("%i, &r");
        while (r = y)
    {
        double volts, init, ending, increment, part=1;
        fputs("What is the voltage?", stdout);
          scanf("%lf", &volts);
        fputs("What is the initial resistance?", stdout);
          scanf("%lf", &init);
        fputs("What is the ending resistance?", stdout);
          scanf("%lf", &ending);
        fputs("What is the increment resistance?", stdout);
          scanf("%lf", &increment);
    
        fputs("case\t"  "voltage\t"  "Initial Resistance\t"  "Ending resistance\t"  "Increment Resistance\n", stdout);
    
        printf("lf"  "%-10lf"      "%-10lf"                 "%-10lf"                "%-10lf\n", part, volts, init, ending, increment);
    
        fputs("would you like to run the program again?", stdout);
        char r, y;  scanf("%i, &r");
    
    ++r;
    }
    
    
    return 0;
    
    }
    Output:
    What is the voltage?1
    What is the initial resistance?2
    What is the ending resistance?3
    What is the increment resistance?4
    case voltage Initial Resistance Ending resistance Increment Resistance
    lf1.000000 1.000000 2.000000 3.000000
    would you like to run the program again?

    End output:

    if i type in any letter except n it reruns the program until i type ctrl c. whats wrong with my loop? and why didn't the spaces pad? thanks for the time.

    Well, I didn't mean to actually use that, just that was the format.

    Found this on the web. . . somewhere. It is handy to have for the print/scan f functions.

    It wasn't the right format, just the format of the formatting. Consult the PDF for more information about formatting controls with printf.
