c - Printing an int value obtained from user -

the problem @ age part, compiler not give me errors when run it prints random number int age

printf("enter name:"); scanf(" %s",&name1); int age; printf("\n\nhow old you?"); scanf(" %d",&age); char gender; printf("\n\nenter gender[male/female]:"); scanf(" %s",&gender); char confirmation; printf("confirmation: name %s , %d years old , , %s.\n\nanswer[y/n]:",&name1,age,&gender); 

here problem.

char gender; scanf(" %s",&gender); 

gender char. is, has memory 1 byte character. using string. have same problem name1 since using & can't sure don't show that.

change like:

char gender[8] // enough fit "female" , terminating null scanf("%7s", gender); 

extra note: scanf bit awkward use prevent buffer safety. may consider fgets sscanf instead.
