No, no, and no. We don't do homework, and the more you ask, the more we will consider banning you. If you want to post an honest attempt to solve the problem, we'll be glad to help you with it, but we won't do it for you.

Re: pls i need help

How about for each number, you save it if it's bigger than the last one?

Re: pls i need help

how would you do it in your head especially if you had a poor memory.
You would loop through your list, examine first number and write it down on a bit of paper.Then you would look at next number if there was one and if bigger you would scrub out whats on the slip of paper and write the new number down. Eventually you would have examined all the numbers and the number on the paper slip will be the biggest number in the collection. Now if you cant figure out how to convert that to c++ dont fear, theres always a call for refuse collectors!

Re: pls i need help

okay umbrella here is your code.this will find the largest number in a given set of numbers.first of all you store the given numbers in an array and then initialise a for loop:-

C Syntax (Toggle Plain Text)
main()
{
int i,j,max,a[100];
printf("\enter the number of elements");
scanf("%d",&i);
for(j=1;j<=i;j++)
{
printf("enter the %d element",j);/*comparing and finding the largest number*/
scanf("%d",&a[j]);
}
max=a[1];
for(j=1;j<=i;j++)
{
if(a[j]>max)
max=a[j];
}
printf("\nthe largest number among the given set of numbers is              %d",max);
}
main()
{
int i,j,max,a[100];
printf("\enter the number of elements");
scanf("%d",&i);
for(j=1;j<=i;j++)
{
printf("enter the %d element",j);/*comparing and finding the largest number*/
scanf("%d",&a[j]);
}
max=a[1];
for(j=1;j<=i;j++)
{
if(a[j]>max)
max=a[j];
}
printf("\nthe largest number among the given set of numbers is              %d",max);
}

Re: pls i need help

indian scorpion dont you like array[0] for some reason. remember in c/c++ arrays are zero based not 1 based.Its possible for that prog to segfault. Also its not a good idea to give homework answers if the OP has shown no effort especially flawed ones.

Re: pls i need help

mr.stoned_coder for your information.the code is executing perfectily.and i have started the counting from 1 so that the program looks more readable and user friendly.

Re: pls i need help

It's actually less readable and less user friendly because every other C/C++ programmer starts arrays at zero.

Re: pls i need help

Ok so you wanna look like a dick!

C Syntax (Toggle Plain Text)
scanf("%d",&i);
for(j=1;j<=i;j++)
{
printf("enter the %d element",j);/*comparing and finding the largest number*/
scanf("%d",&a[j]);
}
scanf("%d",&i);
for(j=1;j<=i;j++)
{
printf("enter the %d element",j);/*comparing and finding the largest number*/
scanf("%d",&a[j]);
}

enter 100
j<=100, 100 is <= 100 so code executes
scanf("%d",&a[100]).... segfault
a[99] is the last element of the array.
