while loop - still need help

I have been working on a problem to enter the first term then a second term.... then add all of the numbers

for example..

enter first term: 1

enter second term: 5

output

1+2+3+4+5 = 14

I was able to get that to work correctly...

now I am trying to do the second half of the program...

to output

1*1*1 + 2*2*2 + 3*3*3 + 4*4*4 + 5*5*5 = answer

this is what i have so far... I think I have the right idea but something like a bracket in the wrong place or maybe too many places

#include<iostream.h>

#include<math.h>

main()

{

int firstnum, secondnum, answer;

int total = 0;

int total2 = 0;

cout<<"Please enter beginning term: ";

cin>>firstnum;

cout<<"Please enter ending term: ";

cin>>secondnum;

while(firstnum<=secondnum)

{

{

cout<<firstnum<<" + ";

total=(total+firstnum);

firstnum++;

}

cout<<" = "<<total<<"\n";

{

cout<<firstnum<<" * " << firstnum<<" * "<<firstnum;

total2 = (firstnum * firstnum * firstnum);

firstnum++;

}

cout<<" = "<<total2<<"\n";

}

}

when i compile I get an error.... expecting a bracket....

suggestions would be appreciated.

thank you

still having looping problems

I am still trying to make a program that:

Enter first term: 1

Enter second term: 4

Output:

1 + 2 + 3+ 4 = answer

1*1*1 + 2*2*2 + 3*3*3 + 4*4*4 = answer

This is the code that I have:

#include<iostream.h>

#include<math.h>

main()

{

int firstnum, secondnum, answer;

int total = 0;

int total2 = 0;

cout<<"Please enter beginning term: ";

cin>>firstnum;

cout<<"Please enter ending term: ";

cin>>secondnum;

while(firstnum<=secondnum)

{

{

cout<<firstnum<<" + ";

total=(total+firstnum);

firstnum++;

}

cout<<" = "<<total<<"\n";

{

cout<<firstnum<<" * " << firstnum<<" * "<<firstnum;

firstnum++;

}

total2+= (firstnum * firstnum * firstnum);

cout<<" = "<<total2<<"\n";

}

}

But instead when I run the program I get:

Please enter beginning term: 1

Please enter ending term: 4

1 + = 1

2 * 2 * 2 = 27

3 + = 4

4 * 4 * 4 = 152

Any suggestions would be really appreciated.

Thank You
