Count words in a txt file

[jackloanshark]

Hello, I am a beginner of c. I wrote a program about counting words in a txt file.But actually there are some error in it and it will stop counting at the first paragraph and just return the number of words i want to count in the 1st paragrah. Can anybody tell what is going wrong in my program? Thank you very much.

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define SIZE 1000
 
char *search(char *, char *);
 
int main()
{
    char string1[SIZE], string2[SIZE], oriword[30], 
         *newword, file1[30];
    int  count;
    FILE *inFile;
 
    printf("Please enter an input file name: ");
    scanf("%s", &file1);
    inFile = fopen(file1, "r");
    printf("\nWhich word do you want to find: ");
    scanf("%s",&oriword);
    while (fgets(string1, SIZE, inFile) != NULL);
    newword = search(string1, oriword);
    count = 0;
    while (newword != NULL)
    {
          count++;
          newword = search(newword + strlen(oriword), oriword);
          printf("%s\n", newword);
    }
 
    printf("\nThe number of %c%s%c appeared %d time(s).\n", '"', oriword, '"', count);  
    fclose(inFile);
    fflush(stdin);
    printf("\nPlease press the Enter key to continue......\n");
    getchar();
    return 0;
}
 
 
char *search(char *string3, char *owd)
{
     int j, k;
     char *tmp;
 
     j = strlen(string3);
     k = strlen(owd);
     for (tmp = string3; tmp <= string3 + j - k; tmp++)
     {         
          if ((tmp == string3 || *(tmp - 1) == ' ' || *(tmp - 1) == '.')
          && strncmp(tmp, owd, k) == 0 
          && (*(tmp + k) == ' ' || *(tmp + k) == '.' || *(tmp + k) == '\0'))
              return tmp;
     }
     return NULL;
}
 
 

i am using win xp, my compiler is dev-c++ 4.9.9.2

Dev C++ has a nice debugger;while debugging,you can use the "watch variable" option,wich lets you check the value of variables in every moment.
Dev C++ debugger only works with single file source code;it will not work with a file included in a .dev project file.

Thanks for your reply. But my program can be complied and run by Dev-C++. It doesn't contain any syntax, logical or runtime error. The error i mean is that the program cannot match my goal --- to count the words in the whole txt file but not just the 1st paragraph. So I need yours help to tell how should i rewrite the program to meet my requirement.

Yes OK I understand that your code does not contain any syntax error(because if it had syntax error ,debugger would not even start);but you should use debugger to search for semantic error as well.
Semantic errors occur when a variable has a value that it should not,or when a variable has a value that it is not expected to have according to the algorithm that you designed.
Semantic errors are the hardest kind of error to look for,and a debugging session should help you veru much.

Thank you for reply. I know where is the error now. Thank you for your patient reply.
