【问题描述】:
任务是:从文件中读取文本并从键盘读取分隔符数组。程序应该搜索文本中的分隔符序列,如果找到 3 次或更多,则将所有奇数字符串交换成一个圆圈。它还应该检测用户输入的所有超过长度限制的单词,但仅限于奇数字符串。 这就是我现在得到的:
#include "stdafx.h"
#include <stdio.h>
#include <conio.h>
int main(void)
{
setlocale(LC_ALL, "Russian"); //entering the text
const int numberOfCharactersToRead = 128;
char* inputText = (char*)(malloc(sizeof(char) * numberOfCharactersToRead));
FILE *fp;
fopen_s(&fp, "D:\texxxt.txt", "r");
if (fp == NULL)
{
printf("nFile not foundn");
system("pause");
return 0;
}
fgets(inputText, numberOfCharactersToRead, fp);
printf("Enter the sequence of delimiters: "); //entering delimiters
const int numberOfDelimitersToRead = 6;
char* delimiters = (char*)(malloc(sizeof(char) * numberOfDelimitersToRead));
int indexer = 0;
for (indexer = 0; indexer < numberOfDelimitersToRead; indexer++)
{
delimiters[indexer] = getchar();
}
//Trying to use strtok in order to devide text into rows (unsuccesful)
char delims[] = "/n";
char *pch = strtok_s(NULL, inputText, &delims);
printf("nLexems:");
while (pch != NULL)
{
printf("n%s", pch);
pch = strtok_s(NULL, inputText, &delims);
}
return 0;
}
int symcount(void)
{ //function searching the quantity of delimiters
char str[20], ch;
int count = 0, i;
printf("nEnter a string : ");
scanf_s("%s", &str);
printf("nEnter the character to be searched : ");
scanf_s("%c", &ch);
for (i = 0; str[i] != ''; i++)
{
if (str[i] == ch)
count++;
}
if (count == 0)
printf("nCharacter '%c'is not present", ch);
else
printf("nOccurence of character '%c' : %d", ch, count);
return (0);
}
我真的不知道如何将文本分成行以及如何使我的程序区分偶数和奇数字符串。我真的很困惑
