Let Us C- Q2.43
Output will be- int main(){ int a =0,b=1,c=3: *((a)?&b&:&a)=a ? b : c; printf("%d %d%d ", a,b,c); }
Output will be-int main(){ int a =0,b=1,c=3:*((a)?&b&:&a)=a ? b : c;printf("%d %d%d ", a,b,c);}

multi dimensional array
Let A be a two-dimensional array declared as follows: A: array[1..23][1..19] of integer; Assuming that each integer takes one memory location, the array is stored in rowmajor order and the first element of the array is stored at the location. Find out the address of the address of the element A[i][j].
