Printing values of array in C

Every time I want to print them I get a segmentation fault(look at the commented code). Why is that?

A) Code did not use protection. Notice that when reading data into str1, should the text length exceed 9, code will cause undefined behavior (UB) as str1[10], as a string can only hold up to 9 characters and a null character.

B) Code did not check the result of sscanf(). Unless 2 fields were scanned, printf("Thirs is : %s\n", str3); will cause UB as it could print an uninitialized character array.

// problematic code

// text input "function2+0x34 -> function3\n"
while (fgets(line, sizeof(line), file)) {  
  char str1[10], str3[10];
  sscanf(line,"%s -> %s", str1,str3);
  printf("First is: %s \n", str1);
  printf("Thirs is : %s\n", str3);

How to fix?

A) Limit input into destination arrays. 9 is the maximum character width to read.

  sscanf(line,"%9s -> %9s", str1,str3);

B) Check sscanf() results

  if (sscanf(line,"%9s -> %9s", str1,str3) != 2) {
    fprintf(stderr, "Scan failure\n");
    return -1;
  }

C) Notice that array str1[] and others may be too small. Increase as needed.

Can I put this values into a 2D array. And then print it. If yes how to do it? I want an output like ...

Of course code can, but this is another question that needs greater detail on OP's goal and really should be one that OP attempts first.

Hint: look into sscanf() format specifiers "%[]", "%n" and "%x"

If still having trouble, some untested code to scan str1[] ...

char f[100]; unsigned addr;
int cnt = sscanf(str1, "%99[^+]+%x", f, &addr);
if (cnt == 1) puts("Only first field found");
else if (cnt == 2) puts("Both fields found");
else puts("Unexpected input");

There are many functions that can be checked for success or failure.
This defines SIZE as 4 but that can be increased as needed.
char str1[SIZE][40] allows up to 4 strings with up to 40 characters each.
The first step is to separate the two initial substrings. Using a scanset, %39[^-] will scan up to 39 characters (prevent writing too many characters into the array memory) and capture all characters that are not -.
strchr tests if the substring contains a + and the substring is parsed as appropriate.

#include <stdio.h>
#include <string.h>

//maximum lines to process
#define SIZE 4

int main(int argc, char* argv[])
{
    char line[256];
    char str1[SIZE][40], str3[SIZE][40];
    char sub1[40], sub3[40];
//        char sub1[SIZE], sub3[SIZE];   //mistake on this line
    int str2[SIZE], str4[SIZE];
    int each = 0;
    int result = 0;
    int loop = 0;

    //check for correct arguments
    if ( argc != 2) {
        printf ( "syntax is program filename\n");
        return 1;
    }

    //check for successful file opening
    if ( ( file = fopen(argv[1], "r")) == NULL) {
        printf ( "could not open file %s\n", argv[1]);
        return 2;
    }
