In C, what is the statement for preprocessor directives AJ Question 2 (10 points) In C, write the preprocessor directive statement to call the library stdio.h AJ Question 3 (10 points) In C, the line that starts a main function that returns an integer value to the operating system. To end execution of the program and return control to the operating system, we use a return 0; O pair of brackets variable preprocessing directive In the following declaration : double x1=1, y1=5, X2=4, y2=7, side 1, side_2, distance; x1, y1, x2, y2, side 1, side 2 and distance are called type specifiers data type constants identifiers The values assigned to variables are called constants identifiers garbage values O memory snapshot In the following declaration : double x1=1, y1=5, x2=4, y2=7, side_1, side_2, distance; x1, y1, x2, y2, side_1, side_2 and distance are called type specifiers data type constants identifiers The following is the correct assignment statement for identifier 'sum' that has double as its type specifier and assigned the value of 10.5 Double sum=10.5; double sum 10.5 double sum; double sum=10.5; The binary operator'%' calculate O the remainder of a division the percentage of a value division multiplication The specifier for variable type integer is %u 0 % 0 % %lf The specifier for input statements for variable type float is %f %lf %d %i
