}

The range for type short is from -32768 to 32767The range for type int is from -
2147483648 to 2147483647The range for type long is from -2147483648 to 214748364
7The range for type float is from 1.17549e-038 to 3.40282e+038The range for type
 double is from 2.22507e-308 to 1.79769e+308The range for type long double is fr
om 0 to 1.#INF
