hello everyone, can anybody help me how to count and display the palindromes
in this randomized letters:

this is my program but it only prints randomized letters and can't count the palindromes words and display it:


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

int max=0;
int copy(char *str,int n);
int rev(char *s);
int palind(char *s);

main(){
int x;
int y[50];
int i=0;

clrscr();

for(i=0; i<200; i++){
srand(time(NULL));

for(i=0;i<=200;i++){

x =rand()%26+97;
y[i] = x%26+97;
printf("%2c", x);
i++;
}
}


for(i=0; i<200; i++){
srand(time(NULL));

for(i=0;i<=200;i++){

x =rand()%26+97;
y[i] = x%26+97;
printf("%2c", x);
i++;
}
}
for(i=0; i<200; i++){
srand(time(NULL));

for(i=0;i<=200;i++){

x =rand()%26+97;
y[i] = x%26+97;
printf("%2c", x);
i++;
}
}
for(i=0; i<200; i++){
srand(time(NULL));

for(i=0;i<=200;i++){

x =rand()%26+97;
y[i] = x%26+97;
printf("%2c", x);
i++;
}
}
for(i=0; i<200; i++){
srand(time(NULL));

for(i=0;i<=200;i++){

x =rand()%26+97;
y[i] = x%26+97;
printf("%2c", x);
i++;
}
}
for(i=0; i<200; i++){
srand(time(NULL));

for(i=0;i<=200;i++){

x =rand()%26+97;
y[i] = x%26+97;
printf("%2c", x);
i++;
}
}
for(i=0; i<200; i++){
srand(time(NULL));

for(i=0;i<=200;i++){

x =rand()%26+97;
y[i] = x%26+97;
printf("%2c", x);
i++;
}
}

printf("\n\nThe PALINDROMES are:\n");
palind(x);
printf("The number of Palindrome is %d",max);
getchar();

}


int copy(char *str,int n) {

char *st;
int i,q;
st=malloc(sizeof(char)*n);
for(i=0;i<=n;i++){
st[i]=str[i];
}
st[n+1]='\0';
x=strlen(st);
if(q>=3&&st[0]!=' '){
printf("%s\n",st);
max++;
}

}


int rev(char *s) {
int i,k,r,len;
len=strlen(s);
for(i=len-1;i>0;i--){
k=0;
r=i;
while(k < r && s[k] == s[r]){
k++;
r--;
}

if(k >= r){
copy(s,i);
}
}
}

int palind(char *s) {
int i,len;
len=strlen(s);
for(i=0;i<len;i++){
rev(&s[i]);
}

getch();
}

Hello,
We already help you to discover palindromes and to count them.
What is the problem, now?

I don't understand why you are doing 7 times the same for loop...
Moreover,

for(i=0; i<200; i++){
srand(time(NULL));

for(i=0;i<=200;i++){

x =rand()%26+97;
y[i] = x%26+97;
printf("%2c", x);
i++;
}
}
- you're using the same i in outer and inner loop -> dangerous.
- y[i]: i goes from 0 to 200. But, y is an array of 50 int -> it crashes

What do you want to do?
