Programming Homework Help

Write assembly functions(.s) that implement the following C functions:

a. bool isStrEqual(const char str1[], const char str2[])

// returns true (1) if the strings match, false (0) otherwise

b.void strConcatenate(char strTo[], const char strFrom[])

// adds the contents of string strFrom to strTo

// note: strTo must have enough space to hold the contents of strFrom and strTo

c. int32_t sumS32(const int32_t x[], uint32_t count)

// returns sum of the values in the array (x) containing count entries.

d. uint32_t countAboveLimit(const int32_t x[], int32_t limit, uint32_t count) // returns number of values in the array (x) containing count entries that are > limit

e. void leftString(char * strOut, const char * strIn, uint32_t length)

// input: array (strIn) containing the input string, and the number of characters to extract (length)

// output: array (strOut) containing up to, but not exceeding length number of strIn characters from the start of the array

// strIn = ‘abcdef’, length = 5 → returns strOut = ‘abcde’

// strIn = ‘abcdef’, length = 7 → returns strOut = ‘abcdef’

f. int32_t find2ndMatch(const char strIn[], const char strMatch[])

// input: array (strMatch) containing the string to find in the array (strIn)

// output: returns the offset within str of the 2nd occurrence of strMatch or -1 if not found

g. void sortAscendingInPlace (uint32_t x[], uint32_t count)

// input: array (x) containing count entries

// output: array (x), with the values sorted in ascending order

h. int16_t decimalStringToInt16(const char * str)

// convert the null-terminated string (str) to a signed 16-bit integer

// treat the string as representing a decimal number

// if a character other than 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, or – is present or the value is out of range, return 0

// the -, if present after the first character should cause the function to return 0

i. uint8_t hexStringToUint8(const char * str)

// convert the null-terminated string (str) to an unsigned 8-bit integer

// treat the string as representing a hexadecimal number

// if a character other than 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, or F is present or the value is too large, return 0.

j. int32_t findCityAligned (const char city[], const BUSINESS7 business[], uint32_t count)

// returns the index of the first entry in the array (business) containing count entries which matches the requested city. If the city is not found, return a value of -1. You can assume that C default alignment is used for this problem.

k. int32_t findCityPacked (const char city[], const BUSINESS7 business[], uint32_t count)

// returns the index of the first entry in the array (business) containing count entries which matches the requested city. If the city is not found, return a value of -1. You can assume that C packing is used for this problem.

Write the solution of each of these functions in a single file hw3.s with functions being callable from a C program. You do not need to send the .c file.
