Answer 1

Program :

# Create a function to print squares of numbers in sequence.
twinprime <- function(n1=2,n2=5)
{
count=0;
cat("The twin Prime numbers are:\n")
for(n1 in 1:n2)
{
x<-n1+2
if(Checkprime(n1) && Checkprime(x)){

count=count+1
cat(n1," ",x)
cat("\n")
}
}
cat("The amount of Twin Prime number are:",count)
}
Checkprime <- function(n)
{
f=0
for(i in 1:n)
{
if(n%%i==0)
f<-f+1
}
if(f==2)
TRUE
else
FALSE
  
}

twinprime(1,100)
