Thread: how to solve this problem of encode?

hihi .. i don know how come this program cannot decode propertly
<code>
#include <iostream.h>
#include <string.h>
void main()
{
int text_length;
char text[100];
char decode_text[100];

int i,k;



char encode[64]="qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXC VBNM1234567890&";




cout<<"enter code: ";
cin.ignore();
cin.getline(text, 100);
text_length=strlen(text);

for (i=0;i<text_length;i++)
{
for (k=0;k<64;k++)
{
if(text[i]=encode[k])
decode_text[i]=encode[k+1];
}
}
k=0;
while(decode_text!='\0')
{
cout<<decode_text[k];
k++;
}


}
