Complete the implementation of the update_bits_2 program. This program will help you learn how to query and update individual bits (or groups of bits) within variables. The program must define several global variables, as follows: • Declare two global variables, each of them suitable to store a single byte. The names of the variables should be in_var_01 and output_var_01. Do not assign values to these variables at the point of declaration. • Declare two global variables, each of them suitable to store a single byte. The names of the variables should be in_var_02 and output_var_02. Do not assign values to these variables at the point of declaration. • Declare two global variables, each of them suitable to store a single byte. The names of the variables should be in_var_03 and output_var_03. Do not assign values to these variables at the point of declaration. • Declare two global variables, each of them suitable to store a single byte. The names of the variables should be in_var_04 and output_var_04. Do not assign values to these variables at the point of declaration. • Declare two global variables, each of them suitable to store a single byte. The names of the variables should be in_var_05 and output_var_05. Do not assign values to these variables at the point of declaration. • Declare two global variables, each of them suitable to store a single byte. The names of the variables should be in_var_06 and output_var_06. Do not assign values to these variables at the point of declaration. • Declare two global variables, each of them suitable to store a single byte. The names of the variables should be in_var_07 and output_var_07. Do not assign values to these variables at the point of declaration. • Declare two global variables, each of them suitable to store a single byte. The names of the variables should be in_var_08 and output_var_08. Do not assign values to these variables at the point of declaration. • Declare two global variables, each of them suitable to store a single byte. The names of the variables should be in_var_09 and output_var_09. Do not assign values to these variables at the point of declaration. • Declare two global variables, each of them suitable to store a single byte. The names of the variables should be in_var_10 and output_var_10. Do not assign values to these variables at the point of declaration.
After declaring the global variables, define function update_bits, as follows: • The function requires no arguments and returns nothing. • Within the function: o Modify the value of bit 5 of global variable output_var_01, such that it is equal to 1 if and only if bit 0 of in_var_01 is set. Leave all other bits unaltered. Do not alter in_var_01. Modify the value of bit 5 of global variable output_var_02, such that it is equal to 1 if and only if bit 6 of in_var_02 is set. Leave all other bits unaltered. Do not alter in_var_02. • Modify the value of bit 6 of global variable output_var_03, such that it is equal to 1 if and only if bits 0,6 of in_var_03 are all set. Leave all other bits unaltered. Do not alter in_var_03. o Modify the value of bit 4 of global variable output_var_04, such that it is equal to 1 if and only if bits 3, 5 of in_var_04 are all set. Leave all other bits unaltered. Do not alter in_var_04. o Modify the value of bit 3 of global variable output_var_05, such that it is equal to 1 if and only if bits 0, 3, 5 of in_var_05 are all set. Leave all other bits unaltered. Do not alter in_var_05. • Modify the value of bit 3 of global variable output_var_06, such that it is equal to 1 if and only if bits 4, 6, 7 of in_var_06 are all set. Leave all other bits unaltered. Do not alter in_var_06. • Modify the value of bit 7 of global variable output_var_07, such that it is equal to 1 if and only if bits 0, 2, 3, 4 of in_var_07 are all set. Leave all other bits unaltered. Do not alter in_var_07. o Modify the value of bit 3 of global variable output_var_08, such that it is equal to 1 if and only if bits 3, 4, 5, 7 of in_var_08 are all set. Leave all other bits unaltered. Do not alter in_var_08. o Modify the value of bit 1 of global variable output_var_09, such that it is equal to 1 if and only if bits 0, 1, 3, 4, 7 of in_var_09 are all set. Leave all other bits unaltered. Do not alter in_var_09. Modify the value of bit 7 of global variable output_var_10, such that it is equal to 1 if and only if bits 1, 4, 5, 6, 7 of in_var_10 are all set. Leave all other bits unaltered. Do not alter in_var_10.
