The below program would give compile error because comma has been used after foo(). Instead, semi-colon should be used i.e. the way it has been used after bar(). That's why if we use semi-colon after foo(), the program would compile and run successfully while printing "GeeksQuiz"

Typically, library header files in C (e.g. stdio.h) contain not only declaration of functions and macro definitions but they contain definition of user defined data types (e.g. struct, union etc), typedefs and definition of global variables as well. So if we include the same header file more than once in a C program, it would result in compile issue because re-definition of many of the constructs of the header file would happen. So it means the following program will give compile error. 

In C, 1D array of int can be defined as follows and both are correct. 

But given the following definitions (along-with initialization) of 2D arrays 

Pick the correct statements.

Which one of the choices given below would be printed when the following program is executed?

The following function computes the value of

^mC_n

correctly for all legal values m and n (m≥1,n≥0 and m>n)

In the above function, which of the following is the correct expression for E?
