Thread: Is this a valid statement?

Code:

for(ii = 0, j = 0; j <= m; ++j, ++ii)
        ++wlenght[truewlenght[j] - 1];

This statement is a part of a program that is not functioning correctly.
Is that maybe a reason?

The program purpose is to print a histogram of the words. This is actually an exercise 1-13 from Kernighan-Ritchie's book.
An eventual other corrections would be apprecieated. Here goes the whole code.
Thanks.

Code:

#include<stdio.h>


int main(void)
{
    int c, i, n, j, m, s, ii, jj, nn, wlenght[150], truewlenght[150]; 
    c = i = n = j = m = s = ii = jj = nn = 0;
    
    for(s = 0; s <= 150; ++s)
    {
        wlenght[s] = 0;
        truewlenght[s] = 0;
    }






    while((c = getchar()) != EOF)
    {
        if(c != ' ' && c != '\t' && c != '\n')
            ++wlenght[i];
        
        if(c == ' ' || c == '\t' || c == '\n')
            ++i;
    }


    n = i;


    for(i = 0; i <= n; ++i) /* Eliminates 0 character array members */
        if(wlenght[i] > 0)
        {
            truewlenght[j] = wlenght[i];
                ++j;
        }


    for(i = 0; i <= n; ++i)
        wlenght[i] = 0;;




    m = j;


    for(ii = 0, j = 0; j <= m; ++j, ++ii)
        ++wlenght[truewlenght[j] - 1]; /* Forms histogram inside the array wlenght */


    
    for(jj = 0; jj < ii; ++jj)
    {
        putchar('|');
        putchar(jj);
        putchar('|');


        for(nn = 1; nn <= wlenght[jj]; ++nn)
            putchar('*');
    }
    
    return 0;
}
