Write a program to reverse an array without affecting special characters.
Note: Given a string, that contains special character together with alphabets ('a' to 'z' and 'A' to 'Z'), reverse the string in a way that special characters are not affected.
Answer:
#include
#include
int isSpecial(char);
int main()
{
char hel[] = "a!!!b.c.d,e'f,ghi";
char *anj = hel;
reverseWord(hel);
printf("%s",anj);
return 0;
}
void reverseWord(char *anj)
{
int r = strlen(anj)-1;
char x;
int l = 0;
while (l='A' && x='a' && x
