Separate tokens from a source program using c programming Saturday, September 14, 2013

Here source.c file contain the source program. And this program only count the printf and scanf. You can add more token in the line where char *word[] = {"printf", "scanf"};.

Tokens.c: Run this code

 /** * Problem: Seperate tokens from a source programe * Author: Md. Mahedi Azad * Date 12-Sep-2013 * */ #include <stdio.h> #include<string.h> int main(){ char line[1000]; char *word[] = {"printf", "scanf"}; int k=0; char seperate[] = " .,("; char *token; int count=0; FILE *fp; printf("\tTokens\t\tTimes\n\t----------------------\n"); while(word[k]!= NULL){ fp = fopen("source.c", "r"); if( fp != NULL ){ while ( !feof(fp ) ){ memset(line, '\0', sizeof( line) ); fgets(line, 255, (FILE*)fp); token = strtok(line, seperate); while( token !='\0' ) { if( strncmp(token, word[k], strlen(word[k])) == 0 ) count++; token = strtok(NULL, seperate); } } fclose(fp); } printf("\t%s \t\t %d\n", word[k], count); count = 0; k++; } return 0; }

Input file as source.c: Stay this file with Token.c
#include <stdio.h> int main(){ printf("Test"); printf("Test"); printf("Test"); return 0; }
