segmentation fault: 11 in C code
c, segmentation-fault
Solution
Arrays are indexed from 0, so the loops should be `for(i = 0; i<9; i++)` and not `for(i = 1; i<10; i++)`
In your case, you probably override part of the stack, but in general, going out of boundaries results in undefined behavior.
Problem
Why am I getting a segmentation fault with this code? ``` /* solver.h header file */ 10 struct options{ 11 unsigned int one:1, two:1, three:1, four:1, five:1, six:1, seven:1, eight:1, nine:1; 12 }; 13 14 15 /* structure to describe a cell */ 16 struct cell{ 17 short value; 18 struct options open_options; 19 }; ``` solver.c: ``` 5 #include <stdio.h> 6 #include "solver.h" 7 8 9 10 11 12 int main(){ 13 struct cell board [9][9]; 14 int i=0,j=0; 15 16 17 for(i = 1; i<10; i++) 18 for(j = 1; j<10; j++) 19 (board[i][j]).value = j; 20 21 for(i = 1; i<10; i++){ 22 for(j = 1; j<10; j++) 23 printf(" %d",(board[i][j]).value); 24 printf("\n"); 25 } 26 return 0; 27 } ``` output: 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 Segmentation fault: 11
