Answer Posted / vignesh1988i

the corrected code is:::

#include<stdio.h>
#include<conio.h>
char a1[50]; //GLOABAL VAR.
void reverse(int);
void main()
{
int count=0;
printf("enter the string :");
scanf("%s",a1);
for(int i=0;a1[i]!='\0';i++)
count++;
reverse(count);
getch();
}

void reverse(int count1)
{
char temp;
static int i=0;
if(i!=count)
{
temp=a1[i];
a1[i]=a1[count1-1];
a1[count1-1]=temp;
i++;
reverse(--count1);
}
else
printf("\nthe reversed string is :%s",a1);
}

Write a program to display all the prime nos from 1 to 1000000, your code should not take time more than a minute to display all the nos.

I need testPalindrome and removeSpace #include #define SIZE 256 /* function prototype */ /* test if the chars in the range of [left, right] of array is a palindrome */ int testPalindrome( char array[], int left, int right ); /* remove the space in the src array and copy it over to the "copy" array */ /* set the number of chars in the "copy" array to the location that cnt points t */ void removeSpace(char src[], char copy[], int *cnt); int main( void ) { char c; /* temporarily holds keyboard input */ char string[ SIZE ]; /* original string */ char copy[ SIZE ]; /* copy of string without spaces */ int count = 0; /* length of string */ int copyCount; /* length of copy */ printf( "Enter a sentence:\n" ); /* get sentence to test from user */ while ( ( c = getchar() ) != '\n' && count < SIZE ) { string[ count++ ] = c; } /* end while */ string[ count ] = '\0'; /* terminate string */ /* make a copy of string without spaces */ removeSpace(string, copy, ©Count); /* print whether or not the sentence is a palindrome */ if ( testPalindrome( copy, 0, copyCount - 1 ) ) { printf( "\"%s\" is a palindrome\n", string ); } /* end if */ else { printf( "\"%s\" is not a palindrome\n", string ); } /* end else */ return 0; /* indicate successful termination */ } /* end main */ void removeSpace(char src[], char copy[], int *cnt) { } int testPalindrome( char array[], int left, int right ) { }
