Explain the ML type for each of the following declarations: a. fun a(x,y) = x+2*y; b. fun b(x,y) = x+y/2.0; c. fun c(f) = fn y => f(y); d. fun d(f,x) = f(f(x))); e. fun e(x,y,b) = if b(y) then x else y;

write a C program that has the following statementsint a,b;a = 10;b = a + fun();printf("With the function call on the right, ");printf(" b is: %d\n",b);b = fun() + a;printf("With the function call on the left, ");printf(" b is: %d\n",b);and define fun to add 10 to a. Explain results.

3. A programmer implemented a swap function in C as follows: void swap (int x, int y) { int temp; = temp X; x=y; y temp; } However when he tried to use the swap function in the main function as given below, it didn't work. int main () { int a-10, b=20; swap (a,b); Explain why this function doesn't work. Suggest a way of fixing it. i. ii.

Write these codes in c language please. Thank you in advance 1. Define a function PrintFeetInchShort(), with int parameters numFeet and numInches, that prints using ' and " shorthand. End with a newline. Remember that "\n" in a string literal starts a new line. Ex: PrintFeetInchShort(5, 8) prints:5' 8"   2. Write a function so that the main() code below can be replaced by the simpler code that calls function MphAndMinutesToMiles(). Original main(): int main(void) { double milesPerHour; double minutesTraveled; double hoursTraveled; double milesTraveled; scanf("%lf", &milesPerHour); scanf("%lf", &minutesTraveled); hoursTraveled = minutesTraveled / 60.0; milesTraveled = hoursTraveled * milesPerHour; printf("Miles: %lf\n", milesTraveled); return 0; }   3. Define stubs for the functions called by the below main(). Each stub should print "FIXME: Finish FunctionName()" followed by a newline, and should return -1. Example output:FIXME: Finish GetUserNum() FIXME: Finish GetUserNum()…
