Hi I was ask to do a code in c wich read the contenent inside a txt file and display it then after display it they wan't me to tokenize those command and interpretate them in c. I have no experience in c if someone can show me how to read a txt and make c do a command i apreciate it. sorry if my english is not good.

this is mi text file

virtual.txt

int x;

printline("<html><body>");
while(x=!10){
printline("<h1>this is a test<\h1>");
x++;
}

printline("</body></html>");


this is my code to display it's contenents

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


int main()
{
    FILE *temp;
int c;
    temp=fopen("virtual","r");
    printf("this is the contents of the file :\n\n");
    while((c=getc(temp))!= EOF)
    printf("%c",c);

fclose(temp);

return 0;

}

if someone can show me how to read a txt

this can be done in lots of ways, I suggest searching for examples using fgets, fscanf, fread etc.

make c do a command

what command?

what command?

if you se the text file has some commands in it(that looks kind of c++) i have to make a function
that reads line per line either using fgets or fscanf and translate it to c.

example my first line in virtual.txt is int x; so I have to create something that detec that integer
and create one.
then the printline and so on, I think this is call tokenizing(something like it)

something like this then:

it would be tokenizing if your going to further divide the strings from the lines,
check some examples using strtok from the string.h header

I was thinking some thing like this

char *something[200];
char *algo[]="int x;"

while ( fgets ( something, sizeof something, temp ) != "\n" )
{
if(something==algo){
int x;}

else
printf("not found")//but i think this is hardcoding
}
