hi

I honestly don't know what you want to do, but I'm guessing you want to parse strings. 

If that's the case then I, like @awneill, suggest you take a look at the CLI library as it parses strings sent over UART:

i want to do the similar thing in nordic using termite 

char ch[80];
int n;
int array[3] ={peripheral 1 ,peripheral 2,peripheral 3};
printf ("enter the peripheral number whom you want to send the msg");
scanf("%d", n);
printf("enter the message you want to send");
scanf("%s", ch);

Again, termite is irrelevant - as far as the Nordic chip is concerned, it's just about bytes sent & received via the UART.

See above post about  "retargetting" (or "retargeting")

using termite mean uart .

how to do that ?

No, it doesn't.
