由线读取线和结构的阵列中存储 [英] reading line by line and storing in an array of structure

问题描述

我要看书由行文本文件中一行行并将其存储在数组中。 txt文件中有一些问题将被要求给玩家！

下面的一些问题！

  1：NAR柑potatisen到欧洲; A：1300 talet; A：1500 talet; C：900 talet; D：1700 talet \\ n
RATT SVAR：乙2：我vilken enhet垫elektrisk跨越; A：安培; B：伏; C：焦耳; D：瓦\\ n
RATT SVAR：一3：起价vilket土地哈日六FATT LEGO; A：德国这家; B：澳大利亚; C：日本; D：丹麦\\ n
RATT SVAR：D
 

其在瑞典的！

我已经做了分割线的地方找到一个分号功能！像这样的：

 无效readline_andsplit（）
{
    焦炭海峡[500];
    字符* PTR; //令牌
    FILE *计划生育=的fopen（gameee.txt，R）;   而（与fgets（STR，500，FP））{//读取500个字符
                  //打印我们的乐趣读
    PTR =的strtok（STR，）; //分裂围绕我们的研究结果    而（PTR！= NULL）//同时还有更多的字符串
    {
        的printf（％S \\ n，PTR）; //打印我们得到了什么
        PTR =的strtok（NULL，）; //并保持分裂
    }   }
    FCLOSE（FP）;}
 

和这里的主要code：

  INT的main（）{
    INT I = 0;
    INT numProgs = 0;
    字符* nrofqeustions [50];
    焦线[80];
    INT J = 0;
    焦炭correctanswer;    FILE *文件;
    文件= FOPEN（gameee.txt，R）;    而（与fgets（行，sizeof的线，档案）！= NULL）{
        nrofqeustions [I] =释放calloc（strlen的（线）+1，1）; //添加每个文件名，nrofqeustions数组
        的strcpy（nrofqeustions [I]，线）;
        我++; //文件nrofqeustions的计数
    }    //检查，以确保进入正确的数组
    //对于（J = 0; J＆下; numProgs + 1; J ++）{
    //的printf（\\ n％S，nrofqeustions [J]）;
    //}    的printf（％S \\ n，nrofqeustions [0]）;
    FCLOSE（文件）;    返回0;
}
 

我希望它产生以下的输出：

  1：NAR柑potatisen到欧洲？
答：1300 talet
 A：1500 talet
C：900-talet
D：1700 talet
 

当用户选择它移动到下一个问题！这是一个测验
我还挺新的我的语言！

下面是我的结构：

 结构测验{
字符的问题[X];
炭中高音[4];
炭correctanswer [1];
};
 

解决方案

 ＃包括LT＆;＆stdio.h中GT;
＃包括LT＆;＆stdlib.h中GT;结构测验
{
    焦问题[50];
    字符* ALT [4];
    炭correctanswer [1];
};诠释主（）{结构测验all_ques [10];
INT I = 0;FILE *海达尔;
海达尔= FOPEN（gameee.txt，R）;
焦炭海峡[500];
字符* PTR;而（与fgets（STR，500，海达尔））//读取500个字符
{
    PTR =的strtok（STR，）; //分裂围绕我们的研究结果
    的strcpy（all_ques [I] .questions，PTR）; //存储问题    PTR =的strtok（NULL，）; //并保持分裂
    all_ques [I] .ALT [0] = malloc的（10）;
    的strcpy（all_ques [I] .ALT [0]，PTR）; //将第一个选项    PTR =的strtok（NULL，）; //并保持分裂
    all_ques [Ⅰ] .ALT [1] = malloc的（10）;
    的strcpy（all_ques [I] .ALT [1]，PTR）; //将第二个选项    PTR =的strtok（NULL，）; //并保持分裂
    all_ques [I] .ALT [2] = malloc的（10）;
    的strcpy（all_ques [I] .ALT [2]，PTR）; //存储第三个选项    PTR =的strtok（NULL，）; //并保持分裂
    all_ques [Ⅰ] .ALT [3] = malloc的（10）;
    的strcpy（all_ques [Ⅰ] .ALT [3]，PTR）; //存储第四个选项    与fgets（STR，500，海达尔）;
    的strcpy（all_ques [I] .correctanswer，STR）; //将正确答案    我++;
}
}
 

抱歉，如果我做了一些假的错误！真正的新和努力学习@Haris

I'm trying to read lines from a text file line by line and store it in an array. the txt file has some question in it which will be asked to the player !

Here's some of the questions !!

1: När kom potatisen till Europa?;A:1300-talet; B:1500-talet; C:900-talet;D:1700-talet\n
rätt svar : B

2: I vilken enhet mats elektrisk spänning ?;A:Ampere;B:Volt;C:Joule;D:Watt\n
Rätt svar: A

3: Från vilket land har vi fått lego?;A:Tyskland;B:Australien;C:Japan;D:Danmark\n
rätt svar : D

Its in Sweden !

I have made a function that splits the line wherever it finds a semicolon! like this:

void readline_andsplit()
{
    char str[500];
    char *ptr;// token
    FILE * fp = fopen("gameee.txt","r");

   while(fgets(str, 500, fp)){            // read 500 characters
                  // print what we read for fun
    ptr = strtok(str, ";");         // split our findings around the " "

    while(ptr != NULL)  // while there's more to the string
    {
        printf("%s\n", ptr);     // print what we got
        ptr = strtok(NULL, ";"); // and keep splitting
    }

   }
    fclose(fp);

}

And here's the main code:

int main() {
    int i = 0;
    int numProgs = 0;
    char* nrofqeustions[50];
    char line[80];
    int j = 0;
    char correctanswer;

    FILE *file;
    file = fopen("gameee.txt", "r");

    while(fgets(line, sizeof line, file)!=NULL) {
        nrofqeustions[i] = calloc(strlen(line)+1, 1);   //add each filename into array of nrofqeustions
        strcpy(nrofqeustions[i], line);
        i++;  //count number of nrofqeustions in file
    }

    //check to be sure going into array correctly
    //for (j=0 ; j<numProgs+1; j++) {
    //printf("\n%s", nrofqeustions[j]);
    //}

    printf("%s\n",nrofqeustions[0]);
    fclose(file);

    return 0;
}

I want it to produce the following output:

1: När kom potatisen till Europa?
A:1300-talet
 B:1500-talet 
C:900-talet
D:1700-talet

When the user chooses it moves on to the next question ! it's a quiz i'm kinda of new to the language !

Here's my struct :

 struct quiz{
char question[x];
char alt [4];
char correctanswer[1];


};

解决方案

#include<stdio.h>
#include<stdlib.h>



struct quiz
{
    char questions[50];
    char* alt[4];
    char correctanswer[1];
};

int main (){

struct quiz all_ques[10];
int i = 0;

FILE *haidar;
haidar=fopen("gameee.txt","r");
char str[500];
char *ptr;

while(fgets(str, 500, haidar))               // read 500 characters
{
    ptr = strtok(str, ";");           // split our findings around the " "
    strcpy(all_ques[i].questions, ptr);    // store the question

    ptr = strtok(NULL, ";");            // and keep splitting
    all_ques[i].alt[0] = malloc(10);
    strcpy(all_ques[i].alt[0], ptr);    // store the first option

    ptr = strtok(NULL, ";");       // and keep splitting
    all_ques[i].alt[1] = malloc(10);
    strcpy(all_ques[i].alt[1], ptr);    // store the second option

    ptr = strtok(NULL, ";");       // and keep splitting
    all_ques[i].alt[2] = malloc(10);
    strcpy(all_ques[i].alt[2], ptr);    // store the third option

    ptr = strtok(NULL, ";");       // and keep splitting
    all_ques[i].alt[3] = malloc(10);
    strcpy(all_ques[i].alt[3], ptr);    // store the fourth option

    fgets(str, 500, haidar);
    strcpy(all_ques[i].correctanswer, str);    // store the correct answer

    i++;
}
}

sorry if i did some dummy mistakes!! really new and trying to learn @Haris
