Assignment 1

FUNCTIONS :

fgets() :-

      this function is used to read string from a file.
      
      if '\n' char is appeared while reading with fgets(). fgets() fails to read further data. so this is disadvatage of 

fputs() :-

      this function is used to write our passed string onto destination file.

fgetc() :-

    this function reads one character from source file.

fputc() :-

    this function writes one character to destination file.

fread() :-

      this function reads a chunk of data from source file.

fwrite() :-

      this function writes a chunk of data to destination file.

fseek() :-

      this function moves the file pointer to desired  position.

sprintf() :-

      sprintf stands for “String print”. Instead of printing on console, it store output on char buffer which are specified in sprintf. 
      eg :-
      
   
      #include<stdio.h>
      int main()
      {
                char buffer[50];
                int k=0
                
                 while (k<5)
                sprintf(buffer, "file%d.txt",k++);
 
                printf("\n %s\n ", buffer);
 
                return 0;
      }
      
     
     o/p of program :- 
      file0.txt
      file1.txt
      file2.txt
      file3.txt
      file4.txt
      
      
  
      
      this above function helped me to generate n no of temp file names dynamically.

• In some versions of my code i was getting some garbage data into my output so one my collegue suggested me that. after declaration of every variable initialize that variable with some value. if i dont do so than there are much more chances of getting garbage in output.

• Give proper names to every variable. so that our code can be more readable.

• How to debug . In the sense if we are getting some wrong output in that case try to put proper messages in our code & see what values we are getting.
