MAX value of a subsequence sum

[begum]

i write a program about finding the max value of a subseqence in a
given sequence. i write but i finf lots of syntax mistakes and i
can't do them in correct. please help me.

Thanks;
Begum

here is the program

#include <iostream>
#include <conio.h>
#include <iomanip.h>
#pragma hdrstop
template <class someType>
class Sum
{
private:
someType arr[100];
public:
void add();
void get_sequence();
};
template <class someType>
void Sum<sumType>::a dd()
{
int i;
cout<<"****PLEA SE GIVE A SUBSEQUENCE WHICH IS TO FIND THE MAX.
VALUE ****\n"<<endl;
cin>>"%d",&d>>e ndl;
}
template <class someType>
void Sum<sumType>::g et_sequence()
{
int maxSum=0;
int thisSum=0;
int j;
for (j=0; j<101; j++)
{
thisSum +=a[j];
if (thisSum maxSum)
{
maxSum = thisSum;
}
else if (thisSum < 0)
{
thisSum=0;
}
return maxSum;
}
}
void main ()
{
void add();
void get_sequence();
}

here is the program

[ from a note in MinGW ]

You probably mean <iomanip>.

Compiler specific. (?).

>template <class someTypeclass Sum{
private:
someType arr[100];
public:
void add();
void get_sequence();
};

>template <class someType>
void Sum<sumType>::a dd(){
int i;
cout<<"****PLEA SE GIVE A SUBSEQUENCE WHICH IS TO FIND THE MAX.
VALUE ****\n"<<endl;
cin>>"%d",&d>>e ndl;

???? What the....?
You can't input to "%d" !!
You can't input to endl !!
[ You can't just mix/replace scanf syntax with iostreams. ]

Try:
cin >i;

}
template <class someType>
void Sum<sumType>::g et_sequence(){
int maxSum=0;
int thisSum=0;

// int j;

Unused except in 'for()', so, why don't you put it in the 'for()'?

// for (j=0; j<101; j++){
for (int j(0); j<101; ++j){

thisSum +=a[j];

There is NO 'a' anywhere!! Did you mean the 'arr[]' in your class?

if( thisSum maxSum ){
maxSum = thisSum;
} // if(>)
else if( thisSum < 0 ){
thisSum=0;
} // else if(<)

return maxSum;

Sure you want to 'return' from inside your loop?

} // for(j)

>} // Sum<sumType>::g et_sequence() end

>void main (){

Ahhh, I see now!! You are using code from the early 1980s!!

int main (){ // main() *always* returns an int!!

// void add();
// void get_sequence();
// [ those just declare some functions inside main. (and never define
them!) ]

Sum<intsum;

sum.add();
sum.get_sequenc e();

return 0;

}

Fix all that and try again. OK?

Note the first error listed and the line number:

error: 'sumType' was not declared in this scope

points to:

template <class someType>
void Sum<sumType>::a dd() <---- points to here

Why do you think the compiler is telling you that 'sumType' is not
declared? (Meaning the compiler doesn't know what a 'sumType' is.

It took me longer than I'd care to admit to figure this one out. :-)
