In CMM or CMMI certified organizations,we assess only the standard software processes of the organization. We do not assess the organizations other functional departments like HR or Admin. Then how can we certify the entire organization as CMM level company?? We have assessed only software related activities. Right. There is no relation with other departments like Accounts, HR or Admin. Then how can we claim that the whole company is a CMM certified company?

main() { int a,b; printf("%d,%d",scanf("%d%d",&a,&b)); } => do u mean above program's output... =>output will be:2,whatever you enter value for b. =>because scanf is a library fn which will return how many arguements it processes, and second value you are right mr.Satya but i found my self unable to understand that for the first time scanf returns the no of successful matches but how for the second time it returns the value of 'b'.while a function should return the same 'r' value every time.
