C Programming language Exercises 1-17

Exercise 1-17 Write a program that prints all input lines that are longer than 80 characters long.

The code is as follows:

#include <stdio.h>//contains information about the standard library. #defineMaxRow 10//the maximum number of rows is 10 rows. #defineMAXLINE 100//the maximum number of characters per line is 100. intGetLength (Charcs[]);intMain ()//defines a function named Main, which does not accept parameter values. {    intc, I, row; CharCs[maxrow][maxline]; //Initializes a character array of 10 rows.      for(i =0; i < MaxRow; i++) {cs[i][0] =' /'; } I= row =0;  while(Row < MaxRow && (c = GetChar ())! =EOF) {        //put each line you enter in the array.         if(c! ='\ n')        {            if(I < MAXLINE-2) {Cs[row][i]=C; I++; }            Else{cs[row][maxline-1] =' /'; }        }        Else        {            //When the line is changed, the last thought of this row is added '% '.             if(I < MAXLINE-2) Cs[row][i] =' /'; //move to the next line. row++; //counter Clear 0. i =0; }    }    if(row = = MaxRow) {printf ("10 lines have been entered to start the statistics ... \ n"); }    //Enter a line with a character greater than 10.      for(row =0; Row < MaxRow; row++)    {        if(GetLength (Cs[row]) >Ten) {printf ("%s\n", Cs[row]);    }} 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. }//gets the length of each line. intGetLength (Charcs[]) {    inti =0;  while(cs[i++]! =' /') ; returni;}

Personal Understanding:

Limit the maximum number of rows to support 10 lines, 100 characters per line, the practice mainly consolidates the use of the character array ' \ s '.
