When I run the following code in C language, my compiler shows the error "xxx has stopped working ".
However, when I take array sizes as 1000 instead of 100000 it runs fine. What is the problem and how can I fix it? If there is some memory problem then how can I take input of 100000 numbers in these arrays without exceeding it?
Code I tried :
int main()
{
int a[100000],l[100000],r[100000],ans[100000],x[100000],y[100000];
/*
some code
*/
return 0;
}
Declare a, l, r, ans, x and y as global variables so that they will be allocated in the heap instead of the stack.
int a[100000], l[100000], r[100000], ans[100000], x[100000], y[100000];
int main()
{
The stack is typically a limited resource. Use dynamic allocation (such as malloc) instead.
Most systems limits the stack to something between one and four megabytes. Since your arrays are well over 2MB you are most likely going over the stack limit of your system.
In C there are a couple of ways to solve that problem:
staticmalloc and friends)
Welcome in stackoverflow ;)
use dynamic allocation (malloc/free) in order to use all your ram capacities.
Most systems have a limited stack size and since your arrays are local(automatic) variables they will be allocated on the stack, so you are very likely overflowing the stack. If you need to allocated large arrays malloc is going to be the better choice.
