This program crashes with a segmentation fault, its supposed to loop over a null terminated string and computer something based on the string.

1) What is wrong with this program?

2) Can you draw a memory map with the variables in this function when it is called with "123". How do the variables change over time as the function executes?

3) what does this function do? whats the constant 48 for?

4) Can you rewrite this program using bracket syntax instead of pointers?

Thank you! Will rate immediately!

main.c 1 2 #include 3 4 int function(char *str) { 5 int result = 0; 6 while(str != '\0') { 7 result *= 10; 8 result += *str-48; 9 str++; 10 } 11 return result; 12}
