• A variable name is any combination of 1 to 31 alphabets,digits or underscores.
• The first character in the variable name must be alphabet or underscore.
• No commas or blanks are allowed within a variable name.
• No special symbol other than an underscore can be used in a variable name.
• The keywords cannot be used as variable names because if we do so we are trying to assign a new meaning to the keyword,which is not allowed by the computer.

Example

int si_t;

char code;

float sum_1;

char ss_3_hg;
