    Smile I needs help on writing a C Program that keeps track of the total amount of pulse a m

    I needs help on writing a C Program that keeps track of the total amount of pulse a meter goes high. When the pulse goes high the count should start.
    Pulse = 0 = P when pulse goes high value changes to 1
    At first K=P then when another pulse comes in K=1 with the first pulse. The when the second pulse goes high P =1 and the following formula would be used to finr the new total amount of pulses.
    K = K + P (2 = 1 + 1)
    Now K = 2 this is now the total amount of pulses
    Another pulse comes in
    K = K + P (3= 2 + 1)
    This should be an infinite loop.
    Then I would compare K to another value R (R is another pulse that will go high) If the value of R goes high it will save the value of K and keep record of the final pulse. But the pulse count should not stop.
    If( R =1;
    K= total pulse
    Else continue)
    Please help me. I have the idea but Iím not 100 percent sure if this will work.

    Good - so try it then.

    Even if it doesn't work, you'll learn something.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    What I have so far

    {
    int pulse = 0;
    int total_pulse =0;
    int result = 0;

    do { if pulse == 1;
    total_pulse=total_pulse +1;

    if{result == 1
    result = total_pulse
    printf("the total pulse is %d \n", total_pulse);

    else

    continue;


    But this would end the loop if result equals to 1. How can I make it total_pulse formual keep tracking the number of pulse.

    If? Or does?? As Salem wrote, you need to actually try, and in the process you will gain insight that just sitting there thinking will not provide.

    For example, from my perspective, this is not a loop, nor does it make much sense. You have three opening opening braces and not a single closing one.

    So, if you write some code that actually compiles and runs without error -- even if at first it does not meet your goals -- you will at least have a realistic starting point, since if your code does not compile and run without error, it is almost ridiculous to discuss what the code does or does not do...it doesn't do anything, the compiler (and other programmers) are just going to perceive it as nonsensical.
