Question

Write a c program that reprints input so that no line is longer than 50 characters. Specifically, for lines less than or equal to 50 characters, simply reprint the line. For lines greater than 50 characters, insert a newline at each 50-character interval.
Note: If the 51st character of a line in the input is a newline '\n', then you should not print it (to avoid unnatural double newlines in the text). Depending on your solution, you may not need extra code for this. So worry about this case last.
Tip: Write your own file with test input for the case where the 51st character is a newline. In the bottom-right corner of Vim, you can see the line and column number of your cursor and plan your 51-character input accordingly.
Furthermore, to give developers feedback on their programs for 50-character-displays, you decide to add additional functionality to your program by displaying the line numbers of all lines over 50 characters long and the total number of these offending lines.
for example:
Total lines over 50 chars: 2
Offending lines: 1, 2, learncli$

Answer 1

Using the knowledge in computational language in C++ it is possible to write a code that reprints prints input so that no line is longer than 50 characters.

Writting the code:

#include<stdio.h>

int main(int argc, char** argv){

   //creating pointer to read a file

   FILE * fp;

   char * line = NULL;

   size_t len = 0;

   ssize_t read;

   int i=0;

   //opening a file

   fp = fopen(argv[1], "r");

   //handling the error condition

   if (fp == NULL){

       printf("File not found..!!");

       return 0;

   }

   int moreThan50 =0;

   //reading a file line by line

   while ((read = getline(&line, &len, fp)) != -1) {

       i = 0;

       if(read >= 50){

           moreThan50++;

       }

       while(i < read){

           if(line[i]!='\n'){

               if(i%50 == 0){

                   printf("\n%c",line[i]);

               }else{

                   printf("%c",line[i]);

               }

           }

           i++;

       }

   }

   printf("\nTotal lines over 50 chars: %d\n",moreThan50);

   printf("Offending Lines: ");

   for(i=1;i<=moreThan50;i++)

       printf("%d, ",i);

   fclose(fp);

   return 0;

}
