i need to find the max position of my program. how can i do that? -
int main()
-
{
-
int j[10],max=0,k;
-
for(k=0;k<=9;k++)
-
{
-
printf("Enter the number:");
-
scanf("%d", &j[k]);
-
}
-
for(k=0;k<=9;k++)
-
{
-
printf("x[%d]=%d\n", k, j[k]);
-
if(max<j[k])
-
{
-
max=j[k];
-
}
-
}
-
printf("The maximum number is %d\n",max);
-
}

You mean to say, you need to figure out the index of a maximum number in an array?
Whats the big deal in it? When you calculate the maximum you assign a position variable to index of the loop. When you are done executing the loop you will also have the position in the array where maximum number is present. -
for(k=0;k<=9;k++)
-
{
-
if(max<j[k])
-
{
-
max=j[k];
-
iMaxPosition = k;
-
}
-
}

Slightly different query but I am using index of variable from array,thats why I am posting it here.
I have this code by which I have to trim the successive two or more white spaces in a string.
For ex.If I enter "India(2WS)wins (2WS)Soccer(2WS )World(2WS)Cup! !"
Here 2WS refers to 2 white spaces.
then output should be "India wins Soccer World Cup!!".
Here is the code I have been working on.I couldn't do it in C.Thats why using library functions.
Every time I run this thing its giving me segmentation fault. - #include <stdlib.h>
-
#include<iostream>
-
#include<string>
-
using namespace std;
-
-
int main()
-
char a[30];
-
string s1;
-
int b[5];
-
cout<<"Enter desired string\n";
-
cin.getline(a,30);
-
s1=a;
-
int n=0,i;
-
for(i=0;i<30;i++)
-
{
-
if(a[i]==' '&& a[i+1]==' ')
-
{
-
n++;
-
b[i]=i;
-
}
-
-
}
-
cout<<"The white spaces in given string are "<<n;
-
cout<<"\n";
-
i=0;
-
while(i<n)
-
{
-
s1.erase(b[i],1);
-
i++;
-
}
-
-
-
cout<<"\nThe new formatted string is \n";
-
cout<<s1;
-
return 0;
-
}
-
Any suggestions,hin ts?
Thanks in advance.
Cheers.
Since you do not know the size of the string, you will need to establish that, with the standard library function sizeof() and use this as the for loop ending condition. There may be more problems in your code which I have not looked for.
This loop is guaranteed to run over the bounds of a: - for(i=0;i<30;i++)
-
{
-
//when i = 29, (i+1) = 30!
-
if(a[i]==' '&& a[i+1]==' ')
-
{
-
n++;
-
b[i]=i;
-
}
-
-
}
Also, I belive you should to use
instead of
using 'i' as your index means you are pretty much guaranteed to overrun the bounds of b as well.
I dont' know if these would cause your segmentation fault, but they certainly won't help.

What if the array contains only negative numbers? The initial value of max should be j[0], not 0. Likewise, the initial value of iMaxPosition should be 0.

#include<stdio. h>
#include<conio. h>
void main()
{
int i=0,j,k,l,m;
char a[20];

{
printf("enter value for sorting");
scanf("%s",&a[k]);
}
for(i=0;i<4;i++ )
{
for(j=i+1;j<4;j ++)
{
if(a[i]>a[j])
{
l=a[i];
a[i]=a[j];
a[j]=l;
