Q30

Consider the following two C code segments. $Y$ and $X$ are one and two dimensional arrays of size $n$ and $n \times n$ respectively, where $2 \leq n \leq 10$. Assume that in both code segments, elements of $Y$ are initialized to $0$ and each element $X[i][j]$ of array $X$ is initialized to $i+j$. Further assume that when stored in main memory all elements of $X$ are in same main memory page frame. Code segment $1:$ // initialize elements of Y to 0 // initialize elements of X[i][j] of X to i+j for (i=0; i<n; i++) Y[i] += X[0][i]; Code segment $2:$ // initialize elements of Y to 0 // initialize elements of X[i][j] of X to i+j for (i=0; i<n; i++) Y[i] += X[i][0]; Which of the following statements is/are correct? S1: Final contents of array $Y$ will be same in both code segments S2: Elements of array $X$ accessed inside the for loop shown in code segment $1$ are contiguous in main memory S3: Elements of array $X$ accessed inside the for loop shown in code segment $2$ are contiguous in main memory
