#arrays
i write this program, during initialization of array i given the size as 11 means the number of elements stored in an array is 11. as we know array is not assigned a value of index 12 and above. but in in the program array a is initialized of index from 0 to 19,my question is how the array is ... i=0;i<20;i++) { a[i]=i+1; } for(i=0;i<20;i++) { printf("%d\n",a[i]); } }
