Actually I have posted 3 answers..Bcoz after posting twice I
found there are some logical errors.Last one is fully
correct..If not please let me know..
i think ths program doesnt not work when the sum is
negative.. cant we not work around it by setting the max as
somelarge negative value and comparing with that??
I came to this website looking for the solution and finally
ended up writing it myself. Hope this is useful for someone
else.
Here is a working solution. Set the array "a" and N_ELEMENTS
accordingly. Some cases are not covered but should be an
easy fix.
#include <stdio.h>
#define N_ELEMENTS 7
int main() {
int a[N_ELEMENTS] = {-1, 2, -3, 2, 0, 5, -11 }; // if
you change the array, make sure you change N_ELEMENTS
int i = 0;
while(a[i] < 0 && i<N_ELEMENTS) {
i++;
}
if (a[i] < 0) {
printf ("DEBUG: array with only negative numbers.
Print the smallest negative number as the sum and we are
done.\n");
}
int sum_p=0, sum_n = 0;
int largest_sum = 0;
while (i<N_ELEMENTS) {
if (a[i] > 0) {
sum_p += a[i];
}
else {
sum_n += a[i];
}
if (sum_p+sum_n > largest_sum) {
largest_sum = sum_p + sum_n;
}
if (sum_p+sum_n <= 0) {
// find the next positive number
while(a[i] < 0 && i<N_ELEMENTS) {
i++;
}
if (a[i] < 0 || i == N_ELEMENTS) {
break;
}
sum_p = 0;
sum_n = 0;
} else {
i++;
}
}
printf ("DEBUG: The largest consecutive sum = %d\n",
largest_sum);
}
Guys..Answer 3 is correct..When there are -ve
numbers..maximum sum is 0.U should not consider any elements
at all..Coz null set which has maximum sum.i.e 0.So the 4th
ans is right.
main()
{
char *a = "Hello ";
char *b = "World";
clrscr();
printf("%s", strcpy(a,b));
}
a. “Hello”
b. “Hello World”
c. “HelloWorld”
d. None of the above
union u
{
union u
{
int i;
int j;
}a[10];
int b[10];
}u;
main()
{
printf("\n%d", sizeof(u));
printf(" %d", sizeof(u.a));
// printf("%d", sizeof(u.a[4].i));
}
a. 4, 4, 4
b. 40, 4, 4
c. 1, 100, 1
d. 40 400 4
union u
{
struct st
{
int i : 4;
int j : 4;
int k : 4;
int l;
}st;
int i;
}u;
main()
{
u.i = 100;
printf("%d, %d, %d",u.i, u.st.i, u.st.l);
}
a. 4, 4, 0
b. 0, 0, 0
c. 100, 4, 0
d. 40, 4, 0
struct point
{
int x;
int y;
};
struct point origin,*pp;
main()
{
pp=&origin;
printf("origin is(%d%d)\n",(*pp).x,(*pp).y);
printf("origin is (%d%d)\n",pp->x,pp->y);
}
