data structures using equality operators have higher precedence than the relational operators shifting once to the left multiplies the number by decision control statements are used to repeat the execution of list of statements printf("% "scanf("% "&num))is valid statement , is valid integer constant printf statement can generate only one line of output stdio is used to store the source code of the program the closing brace of main(is the logical end of the program the declaration section gives instructions to the computer any valid printable ascii character can be used for variable name underscore can be used anywhere in the variable name void is data type in all arithmetic operators have same precedence the modulus operator can be used only with integers the calling function always passes parameters to the called function the name of function is global no function can be declared within the body of another function the operator retrieves the lvalue of the variable unary increment and decrement operators have greater precedence than the dereference operator on -bit systemsan integer variable is allocated bytes fill in the blanks was developed by the execution of program begins at in the memorycharacters are stored as return returns to the finds the remainder of an integer division sizeof is operator used to calculate the sizes of data types is also known as forced conversion is executed when the value of the variable does not match with any of the values of the case statement function prints data on the monitor program ends with causes the cursor to move to the next line variable can be made constant by declaring it with the qualifier at the time of initialization operator returns the number of bytes occupied by the operand the specification is used to read/write short integer the specification is used to read/write hexadecimal integer to print the data left-justifiedspecification is used after the function is executedthe control passes back to the function that uses another function is known as the the inputs that the function takes are known as function definition consist of and in methodaddress of the variable is passed by the calling function to the called function size of character pointer is pointer does not point to any valid memory address the appears on the right side of the assignment statement the operator informs the compiler that the variable is pointer variable
