i m getting RT error.can anyone tell me why?


#include <stdio.h>
#include <string.h>


int main()
{
char msg[103];

while(gets(msg))
{
int len = strlen(msg)-1;

int temp=0;

while(len>=0)
{
if(msg[len]>='0' && msg[len]<='9')
{
temp = (int)msg[len] - '0';

if(len-1>=0)
{
temp = temp ...

hello, below is a very simple code of this problem.it provides the correct output for smaller numbers but not for big numbers.can
any one tell me why it is happening?

#include <stdio.h>
#include <stdlib.h>

int main()
{

int n;

char num[100],*p;

while(1)
{
gets(num);

n = atoi(num);

if ...

#include <stdio.h>

int main()
{
int test;
char str[100];
scanf("%d",&test);
//fflush(stdin);
for(int i=0;i<test;i++)
{
gets(str);

int j=0,count=0;

while(str[j]!='\0')
{

if(str[j]==' ')count+=1;
else if(str[j]=='a' || str[j]=='d' || str[j] == 'g' || str[j] =='j' || str[j]=='m' || str ...

}

}
void print(int n)
{
int i;
for( i=2 ; i <= n/2 ;i++)
{
if(prime(i))
{
