Answer :

Compiler Error : Type mismatch in redeclaration of
function display

Explanation :

In third line, when the function display is
encountered, the compiler doesn't know anything about the
function display. It assumes the arguments and return types
to be integers, (which is the default type). When it sees
the actual function display, the arguments and type
contradicts with what it has assumed previously. Hence a
compile time error occurs.

Answer / pratibha

this problem of type mismatching can be solved by declaring display function as a first line inside main() so that compiler will know that display is of type void and then it will resolve type mismatch while encountering calling function of display.

plz tell me the solution.......... in c language program guess any one number from 1 to 50 and tell that number within 8 asking question in yes or no...............
