Answer:
int age;
age=18;
float weight;
weight=114.5F;
Step-by-step explanation:
int age; \\ it is declared as integer because 18 is an integer value
age=18; \\ initialized as 18 is stored in the variable 'age'
float weight; \\ weight is declared as float because it's value is floating or decimal value which cannot be declared as integer value
weight=114.5F; \\ F shows that it's single floating type value of 32 bits, if F is not written then it means it double floating type value which is 64 bits long
