Compiler DesignCode Generation and OptimizationmediumMCQ2 marks

For a C program accessing X[i][j][k], the following intermediate code is generated by a compiler. Assume that the size of an integer is 32 bits and the size of a character is 8 bits. t0 = i * 1024 t1 = j * 32 t2 = k * 4 t3 = t1 + t0 t4 = t3 + t2 t5 = X[t4] Which one of the following statements about the source code for the C program is CORRECT?

AX is declared as “int X[32][32][8]”.BX is declared as “int X[4][1024][32]”.CX is declared as “char X[4][32][8]”.DX is declared as “char X[32][16][2]”.
