I think using push and pop you can do it.

int i, j;
char c[],y[];
c[i]=get char();
push;
pop
y[j]=put char();

while (c[i] !=
)
begin
if(c[i]=y[j])
print(both strings are equal);
else
print ("both are not equal");
end

#include <Stdio.h>
void main()
{
chr *s ,*t;
int i;
fp=fopen("File Name "+b);
fscanf(fp,"%s",s);
*s=*t;
while(*t!=NULL)
{
t++;
i++;
}

while(i--)
printf("%c",*t)

printf("%c",*t);
