C Programming language Exercises 1-18

Practice 1-18 Write a program that removes spaces and tabs at the end of each input line and removes rows that are completely blank.

The code is as follows:

#include <stdio.h>//contains information about the standard library. #defineMAXLINE 10//the maximum number of characters per line is 1000. intGetlineCharLine[],intmaxline);intMain ()//defines a function named Main, which does not accept parameter values. {    intLen; inti; CharLine[maxline];  while(len = getline (line, MAXLINE)) >0)     {        intc =0; //loops forward the character array from the back.          for(i = len-1; I >=0; i--)        {            if(Line[i] = ='\ t'|| Line[i] = =' ')//if the last character is a tab, the position is set to. Line[i] =' /'; Else  Break;//if the last character is not a tab or a space, the loop stops. } printf ("%s", line);    } getchar (); //prevent the console from flashing through, you need to accept any characters after you close the console.     return 0;//returns a shape to the execution environment, and 0 represents a successful execution. }intGetlineCharS[],intLim) {    intc, I;  for(i =0; I < Lim-1&& (c = GetChar ())! = EOF && c! ='\ n'; ++i) {s[i]=C; if(c = ='\ n') {S[i]=C; ++i; }} S[i]=' /'; returni;}

Personal Understanding:

The main practice is the Flashback Loop array, and match the last one, if the space or tab is replaced by '.
