Answer 1

See this here is program for int and float you can also check for string and char

#include<stdio.h>
#include<string.h>

int main()
{
char number[10];
int flag=0;
int length ;

printf("Enter a number \n");
scanf("%s",number);
length=strlen(number);
while(length--)
{
if(number[length]=='.')
{
flag=1;
break;
}
}
if(flag)
printf("Floating point\n");
else
printf("Integer\n");

return 0;
}

You can also use the is_same type predicate
I.e.

int a; char b; float c;

is_same<decltype(a),int>::value;//true

is_same<decltype(b),int>::value;//false

is_same<decltype(c),int>::value;//false
