Thread: Please, Need Help: Counting/Array.

Hi all,

Im kinda stuck at determine how many of these 250 numbers are less than 356; here's my coding

Code:

#include<stdio.h>#include<math.h>
#define N 250


int main()
{
float a[N]={811.594,155.670,80.859,94.000,0.262,25.623,457.023,984.578,134.533,41.242,65.121,8.639, 9.048,50.725,367.316,665.240,0.310,6.573,44.645,0.895,2.097,542.671,0.801,9.622,699.939,
860.123,7.442,572.632,347.332,4.520,2.346,899.460,9.257,280.994,33.103,6.917,63.084,2.147, 602.037,34.400,207.035,610.862,510.798,384.195,66.511,73.813,28.353,0.455,642.567,592.365,

 int c=0; int i; int count[250]; for (i=0;i<N;i++) {
c=a[i]; if (c<356) { count[c]=0;
count[c]++;
}
}


printf("There are: %d numbers less than 356\n",count[c]);
return 0;

}

You forgot to initialise count to 0.

WOW!!! your indenting, newlines, EVERYTHING is a mess!!!

thats 1, 2 your define is not needed just change N to 250, 3 your second array is not needed, as well as useless.

basically fix the formating, then just use a counter to count +1 for each one less then 356


//edit//

ok i missed the count being zeroed, but it is ok, because it seems another new user has not read the policies, and decided to do it for you

Sigh. 0x47617279, please do not do other people's homework for them. I saw your code dump and assumed that you were the original poster updating his/her code attempt, so my post pointed out a problem with your code that you have since corrected.

I don't understand what "count++" does ?
