Problem 5 (8 points): complete the code Complete the C code snippet below to open a file passed to a program as «argc-1> from the command line for reading, program character in the file and adds up the total number of cargc-2> characters read to count. Read characters until the Eor is reached. Fill in the code where blank so the code executes and works correctly. Example: ./a.out ThisSourceCode.c a >> returns: Num of e's: tincludecstdio.h> tinclude int main int argc, char arg) itt fprintf (stderr, "zong nunber of arguments td in", arge) return EXIT FAILORE: 1 FILL IN HERE 1 FILE *in- Eopen t Lf (in NULL) tprintf(atderr, "Could not open fileln") return EXITFALURE; - /* read character, add one to count if matches the letter g int count 0 char c. c2: e2argv [21 101a /e complete code below here FILL IN HERE 1 //// TLLIN HERE //// while / end code/ printt "Num of sc's: dn",c2, count) return ExXIT SUCCESSExplanation / Answer
argc and argv are basic member variables passed in main function
where argc contains the 'number of arguments' can be passed-on
and argv contains the 'vector of arguments'
As per Question there are two arguments
argc (1) holds File Name (which is default)
argc(2) holds the character count
First Fill Statement could be
if (argc != 2) //If argument count is not 2 then throw error and return Failure
{
}
Second Fill Statement Could be
FILE *in=fopen("ThisSourceCode.c","r"); //Open ThisSourceCode.c in read mode
Third Fill Statement Could be
while (1){
c = fgetc(in);
if (c == '@')
{
count++;
}
if ( feof(in) )
{
break; //If you read until end of file , break from the while loop
}
}
fclose(in)
/* end code */
printf("Num of %c's: %d ", c2, count);
return EXIT_SUCCESS;
}
