So I have this code:

char inte[10];

    while(j<noinput) {

            fscanf(circuit,"%s",inte);

            vararray[count]=inte;

            count++;

            j++;

    }

However when I print the contents of the array like this:

for (h=0;h<noinput+2;h++){

            printf("%dth variable: %sn",h,vararray[h]);

    }

The elements past the first two (which are reserved for special elements) are all equal to the LAST string that I had taken in from fscanf earlier. I have no idea how one of the strings from fscanf could be equal to multiple slots in the array when I am only setting

vararray[count]=inte;

Shouldn't this mean that each element of the array will be different since I am incrementing count every time? I am so confused. I also tried doing:

 fscanf(circuit,"%s",vararray[count]);

But this also did not work and gave me null elements for certain indexes.

you are doing something too wrong. By "vararray[count]=inte;" you are doing pointer assignment so all of your vararray is getting filled by same string. I am guessing you are new to C so I will answer due to that. Correct way would look something like below

Fixed size solution:

char vararray[ROWCOUNT][BUFFERSIZE];

for(count=0; j<noinput; ++count, ++j) {

    fscanf(circuit,"%s",(char*)vararray[count]);

}

With dynamic memory management

char * vararray[ROWCOUNT];

for(count=0; j<noinput; ++count, ++j) {

    vararray[count] = (char*)malloc(BUFSIZE);

    fscanf(circuit,"%s", vararray[count]);

}

I want to warn you in the way of becoming an expert on C nowadays is somewhat madness , i mean unless you have another choice. Examples below I put and the thing you wrote are completely unsafe and unsecure...

You're not copying the string. Here's what's happening:

char *vararray[462]; // declare an array of string pointers

char inte[10];       // declare a char array (to function as a string)



for (int i = 0; i < 462; i += 1) {

    // do something

    vararray[i] = inte;

}

This is causing all of the items of vararray to point to the memory also referred to as inte... but you're overwriting that each time! Instead, do something like this:

#include <string.h>  // write me at the top, outside main()!



char vararray[462][10]; // declare an array of strings (max length 9)

char inte[10];       // declare a char array (to function as a string)



for (int i = 0; i < 462; i += 1) {

    fscanf(circuit,"%10s",inte);  // use buffer size to make xscanf safer

    strncpy(vararray[i], inte, 9);  // copy inte, making sure not to buffer overflow!

    vararray[i][9] = '';  // if inte is too big, a null byte won't be added to the end of the string; make sure that it's there

}

This copies the string! Your problem should go away when you do this.
