When I compile the program with Codeblocks (GNU gcc compiler) it gives me this error: Process returned -1073741571 (0xC00000FD)
I tried it without the binary search and it works, but I can't understand why when I insert the binary search it gives me this error.
But if I compile it with another compiler (I tried on mine university online compiler) it works very well.
#include <stdio.h>
#include <stdlib.h>
int main()
{
int n;
int v[n];
int i;
int aux;
int j;
printf("Quanti numeri vuoi inserire? \n");
scanf("%d",&n);
for(i=0;i<n;i++){
printf("%d: ",i);
scanf("%d",&v[i]);
}
for(i=0;i<n;i++) {
printf("%d,",v[i]);
}
printf("\n");
for(j=0;j<n-1;j++) {
for(i=0;i<n-1;i++) {
if(v[i]>v[i+1]) {
aux = v[i];
v[i] = v[i+1];
v[i+1] = aux;
}
}
}
for(i=0;i<n;i++)
printf("%d ", v[i]);
//Binary search
int alto, basso, pos, ele, k;
alto = 0;
basso = n-1;
pos = -1;
printf("Mi dia un elemento da cercare:\n");
scanf("%d",&ele);
while(alto<=basso && pos==-1){
k=(alto+basso)/2;
if(v[k]==ele)
pos=k;
else
if(v[k]<ele)
alto=k+1;
else
basso=k-1;
}
if(pos==-1)
printf("Il numero inserito non e' presente");
else
printf("L'elemento e' presente in posizione %d del vettore", pos);
return 0;
}
int n;
int v[n];
you have undefined behaviour(UB) here.
you declare a VLA with the size set by not initialized variable n
.
So answering the question
Why only codeblocks give me return error(0xc00000FD)
the answer is : because it does. It is not predictable.
