Answer 1

It's also better to format your code so it's easier to read:

int main()
{
int a;
char ms, sex;

printf("Enter the age , martial status in y and n and sex in f and m:");
scanf("%d%c%c",&a,&ms,&sex);

if (ms == 'y')
{
printf("insured");
}
else if (ms == 'n' && sex == 'm' && a > 30)
{
printf("insured");
}
else if (ms == 'n' && sex == 'f' && a > 25)
{
printf("insured");
}
else
{
printf("not insured");
}
getch();
}

Answer 2

Use else if instead of if else:

if(..){
//
}
else if(...){
//
}
else if(..){
//
}
else{
//
}

Answer 3

use "else if" instead of "if else"
