Q.4 A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. Given the C code and memory content mapping shown in Figure Q.4, complete the Table Q.4 to predict the value after program execution. RAM #include void calculate_average(char mark[], float "average, int size) 0x0010 0000 { for (int i=0; i< size; i++) { *average = "average + mark[i]; 0x0020 0000 average_mark } "average = "average / size; 0x0030 0000 ptr FLY int main() { 0x0040 0000 mark[0] char mark[5]=(50, 80, 95, 34, 99}; float average_mark = 0; mark[1] float *ptr=&average_mark; calculate_average(mark, ptr, 5); mark[2] mark[3] return 0; mark[4] Figure Q.4 Table Q.4 Variable Value a) ptr b) &ptr c) *ptr d) &mark[2] e) average_mark

In the C programming language, a pointer is used to store the ADDRESS of a data value. True False

Segmentation: Select all of the following statements that are true. In segmentation, a logical address always has a length of 32 bit. In order to translate logical into physical addresses, the memory management unit uses the segment part of the logical address to determine the start address in the segment table and adds the offset to this to get the physical address. In segmentation, the logical address consists of a segment part and an offset. The segment length is limited by the maximum possible segment number. When applying segmentation, processes are only allowed to access the memory within their segments. Segments can be assigned access rights and privilege levels.

Assembly language Part 1: When a variable is stored in memory, it is associated with an address. To obtain the address of a variable, the & operator can be used.  Write a C program addressOfScalar.c by inserting the code below in the main function. Questions:     1) Run the C program, attach a screenshot of the output in the answer sheet. 2) Attach the source code in the answer sheet 3) Then explain why the address after intvar is incremented by 4 bytes instead of 1 byte.
