Change your code to

#include
int  main()
{
int age;
char sex;
char name[20];
char status;
printf("Enter your last name\n");
// scanf("%s", &name);
fgets(name,20,stdin);

printf("Enter your age\n");
scanf("%d", &age);

printf("Enter sex (M/F)\n");
scanf(" %c", &sex);


printf("your status,married, single,irrelevant (M/S/I)\n");
scanf(" %c", &status);
if(age>=16 && sex=='M')
printf("hello, Mr %s\n", name);
if(age<16 && sex =='M')
printf("hello, Master %s\n", name);
if(sex=='F' && status=='M')
printf("hello, Mrs %s\n", name);
if(sex=='F' &&(status=='S' ||status=='I'))
printf("hello,miss %s\n", name);
return 0;
}

Here, I have added an extra space before the format specifier %c, to accommodate any previous input like newline (\n).
Another alternative method is to use getchar() immediately before you take any character input.

Also, if you perform string input with scanf, it will not read the input after encountering a whitespace. So, instead use fgets for taking any string input which might contain spaces.

Another thing I changed in your code (trivial) is int main() and return 0.
