write a program to find the area under the curve y=f(x) between x=a and x=b integrate y=f(x) between the limits of a and b

Both malloc & new functions are utilized for dynamic memory allocations & the basic difference is: malloc need a special "typecasting" while it allocates memory for eg. if the poin
