For example: # Include Int swpint (int * a, int * B){Int C;C = *;* A = * B;* B = C;Return;}Void main (){Int e = 12;Int F = 89;Swpint ( E, F );Cout }This definition is correct, but a compilation error occurs if the following definition is used: # Include Void main (){Int e = 12;Int F = 89;Int swpint (int *
