Which of the following is true?An array can have elements of different data types.Array elements can be accessed and modified(elements can be added or removed) only at the ends of the array while any elements of the stack can be accessed or modified randomly through their indices.Array is a dynamic data structure whose size can be changed while stacks are static data structures whose sizes are fixed.Elements of a linked-list can be accessed only sequentially.14. What is a dangling pointer?Points to addressNone of AbovePoint to garbage ValuePoints to nothing15. Predict the Output : float a = 0.1;if(a==0.1)printf(“Yes”);elseprintf(“No”)NoYes16. The difference between variable declaration and variable definition isDeclaration associates type to the variable whereas definition associates scope to the variable.A declaration is used for variables and definitions is used for functions.Declaration associates type to the variable whereas definition gives the value to the variableDeclaration and definition are the same.
