Variables and Memory Use

Reminder: Assume a TM4C123 is being used unless specified otherwise.

1. For each declaration, indicate how many bytes will be allocated in memory

i)long input_num2;

ii)int sensor_readings[10];

iii)unsigned short scan_data[20][40];

1. For each, indicate the value of my_length after executing each fragment of C code. Function strlen is a standard C library function. Specify N/A if the value of my_length cannot be determined.

i) my_length is .

char msg[] = CPRE288;

int my_length = 0xFFFFFFFF;

my_length = strlen(msg);

ii) my_length is .

char msg[7] = CPRE288;

int my_length = 0xFFFFFFFF;

my_length = strlen(msg);

iii) my_length is .

char msg[100] = {C,P,R,E,,2,8,8,};

int my_length = 0xFFFFFFFF;

my_length = strlen(msg);

iv) my_length is .

char msg[] = {5, 7, 10, 0, 9, 2, 0, 3, 5, 77, 23};

int my_length = 0xFFFFFFFF;

my_length = strlen(msg + 4);
