C++

Write a C program to work on pointers. In main () you will first sum and set the initial Declare five integer variables named as a, b, values for a, b, c, as 10, 20, 30, respectively . c, temp, . Declare three integer pointers named as pa, pb, pc. These pointers shouled initially hold the addresses of variables a, b, c, respectively Declare three integer pointers to pointers as ppa, ppb, ppe. These pointers to pointers should initially hold the addresses of pointers pa, pb, pc, respectively . . If needed for the below tasks, you can declare other variables as well as pointers later.. . Now implement the following tasks in the main ) o Write the necessary statements to print the values of a, b, c by just using o Write the necessary statements to find the sum of the values in a, b, c by o Write the necessary statements to exchange/print the values in a and b, by o Write the necessary statements to exchange the values/addresses in pa and pb a, pb, ppc (direct, indirect, indirect indirect access) just using a, pb, ppc, sum. Then print sum. just using pa, ppb and maybe temp. Then print a and b. by just using pa, ppb and maybe a temp pointer that you can declare. Then print the values of a and b by directly using a and b as wells as indirectly by using *pa and *pb. Explain what happens here, why the values of a and b did not change when we access them directly while it seems the changed when we access them indirectly. Type your explanation as a c comment in your program after the printf statements. .Now copy/paste the following functions before your main O void increaseA (int val) t val++i void increaseB (int 'pval) f pval++: void increasec(int "pval) f pval++: void increaseD(int "pval) f(pval)++
