Answer #1 
All four arrays are structurally equivalent.

Under name equivalence, array D is incompatible with the others. 
Under strict name equivalence A and B are also incompatible with C 
under loose name equivalence A, B, and C are all mutually compatible.

    C++Implement only (source code) a program to determine whether two two-dimensional arrays are equivalent or not. Two arrays are equivalent if they contain the same values in any order. The program main method defines two two-dimensional array of size 3-by-3 of type integer, and prompts the user to enter integer values to initialize the arrays. The main method calls method isEquivalent()that takes two two-dimensional arrays of integer and returns true (boolean value) if the arrays contain the same values in...

    C code only! Complete this function so that the function str2int convert the char array s into its equivalent integer value. The char array has only digit characters of{0, 1, .., 9}and ’\0’.And the first element is not 0, which means, the integer string in the char array is of base 10. For example, if we pass chars[] = ”123” intostr2int, then it should return 123.Close the braces when you are done int str2int(char s[]){
