Question
Please solve using C language
The function get_tokens gets a string str, and a char delim, and returns the array with the tokens in the correct order. The length of the array should be the number of tokens, computed in count_tokens.
char** get_tokens(const char* str, char delim);
For example:
●くろまる get_tokens("abc-EFG--", '-') needs to return ["abc","EFG"]
●くろまる get_tokens("++a+b+c", '+') needs to return ["a","b","c"].
●くろまる get_tokens("***", '*') needs to return either NULL or an empty array.
Note that the returned array and the strings in it must all be dynamically allocated.

- use c++ Programming language Write a program that creates a two dimensional array initialized with test data. Use any data type you wish . The program should have following functions: .getAverage: This function should accept a two dimensional array as its argument and return the average of each row (each student have their average) and each column (class test average) all the values in the array. .getRowTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The function should return the total of the values in the specified row. .getColumnTotal: This function should accept a two dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array.

Notes Create the square by filling the numbers entered from left to right, top to bottom. Input validation - Do not accept numbers outside the range. Do not accept repeats. Must use two-dimensional arrays in the implementation. Functional decomposition — Program should rely on functions that are consistent with the algorithm.arrow_forward
