which contain:
2

我写了一个C文件,将 Members.txt
读入 char w [100];
数组中,例如:
i had written a C file to read Members.txt
into char w[100];
array like:
int main()
{
int i = 0, line = 5;
char w[100];
char f[20];
char k[15];
FILE *myfile;
myfile = fopen("Members.txt","r");
if (myfile== NULL)
{
printf("can not open file \n");
return 1;
}
while(line--){
fscanf(myfile,"%s",&w[i]);
i++;
printf("\n%s", &w[i]);
}
fclose(myfile);
return 0;
}
但是,我需要将 Members.txt
的每一行换行逐行保存到不同的数组中.
but ,i need every newline ofMembers.txt
to be saved into different array line by line.
推荐答案
如果要读取文件并将其存储在数组中,则可以采用以下解决方案:无法存储在数组中,但是可以存储在数组的内部.在这里,我使您可以访问100行文本文件.无论如何,这是代码:
Here is the solution if you want to read the file and store inside array, You cannot store inside array, but you can store inside structure of array. Here I make you can access 100 lines of text file. Here is the code anyway:
#include <stdio.h>
//Use Structure to store more than one data type
//Since your file not only consist of string, it also have int
struct members
{
char a[100];
char b[100];
long long int c;
long long int d;
};
//Here I make 100 line so that you can read 100 line of text file
struct members cur_member[100];
int main(void) {
FILE *myfile = fopen("Members.txt", "r");
if (myfile == NULL) {
printf("Cannot open file.\n");
return 1;
}
else {
//Check for number of line
char ch;
int count = 0;
do
{
ch = fgetc(myfile);
if (ch == '\n') count++;
} while (ch != EOF);
rewind(myfile);
//Since you put 2 earlier in the member.txt we need to dump it
//so that it wont affect the scanning process
int temp;
fscanf(myfile, "%d", &temp);
printf("%d\n", temp);
//Now scan all the line inside the text
int i;
for (i = 0; i < count; i++) {
fscanf(myfile, "%s %s %lld %lld\n", cur_member[i].a, cur_member[i].b, &cur_member[i].c, &cur_member[i].d);
printf("%s %s %lld %lld\n", cur_member[i].a, cur_member[i].b, cur_member[i].c, cur_member[i].d);
}
}
}
这是结果:

Press any key to continue . . .
该程序将读取您当前的文件,而我只是将其打印出来以显示其工作原理.您可以访问信息并编辑文件.就是这样.
This program will read your current file and I just print it, to show it works. You can access the information and edit the file. Thats all..
