在C中使用Strcmp

Question

I am trying to search for key words from in a text document I have tried to exclude white space, new lines, and tabs. I am able to read inputs from the file but I can not get my strcmp and the counter to change. I tried to use printf statements to locate the issue but I am still lost. If its a syntax issue let me know. Any help would be appreciated.

Heres the block of code

FILE *file2 = fopen( argv[2], "r");

if (file2 == NULL) {
    printf("\nFile 2 could not open\n");
} else {
    do {
        // treat all new line as spaces.   
        x = fgetc( file2 );

        if (x == '\n') {
            x = 32;
        }

        if (x == '\t') {
            x = 32;
        }

        if(x != 32 ) {
            temp[l] = x;

        } else { 
            temp[l] == '\0';

            printf("\t%s", temp);

            for(a=0; a < countw; a++) {
                p = strcmp(swords[a].word,temp);
                if (p = 0) {
                    swords[a].count++;
                }
                printf("\nstop%i\n",a);
            }

            for(b=0; b<l; b++) {
                temp[b] = '\0';
            }
            l = 0; 
        }
    } while (x != EOF);
}

fclose(file2);

It think your problem is right here:

if(p = 0 ) 

It should be:

if(p == 0 ) 

Turn up your compiler warning level enough (like -Wall in gcc) and you may get a warning for unintended assignments.
