C++ pipe process not terminating - process

Question

I made a program that takes two commands typed in by the user and pipes the first into the second. It works fine if real commands are entered but I'm having a problem getting my error check to work when I just enter random words. In most places of my code where I use exit() the process terminates fine but within the two child processes rs1 and rs2, I cannot exit. I'm new to processes so I'm not sure how to do this correctly. Can someone help?
int main()
{
while(true)
{
int argc1=0,argc2=0,rs1,rs2,pipefd[2];
char input1[80],input2[80],*argv1[6],*argv2[6],*p1,*p2;
//*Big block of code that receives input goes here*
pipe(pipefd);
rs1=fork();
rs2=fork();
if(rs1==0)
{
close(pipefd[0]);
close(1);
dup(pipefd[1]);
close(pipefd[1]);
rs1=execvp(argv1[0],argv1);
if(rs1==-1)
{
perror(argv1[0]);
exit(rs1); //Here is where I'm having the problem
}
}
if(rs2==0)
{
close(pipefd[1]);
close(0);
dup(pipefd[0]);
close(pipefd[0]);
rs2=execvp(argv2[0],argv2);
if(rs2==-1)
{
perror(argv2[0]);
exit(rs2); //Here also does not work correctly
}
}
close(pipefd[0]);
close(pipefd[1]);
wait(&rs1);
wait(&rs2);
}
return 0;
}
