1 Expressions and Statementst t Expression C Programming Lecture 6 : Operators Combination of constants,variables,operators, operators and function calls a+b 3.0*x tan(angle) Statement An expression terminated with a semicolon sum = x + y + z; printf( Dragons! ); Lecture notes : courtesy of Ohio Supercomputing Center, and Prof. Woo and Prof. Chang Assignment Operator Arithmetic ti operators The equal sign = is an assignment operator Used to give a variable the value of an expression x=34.8; sum=a+b; slope=tan(rise/run); midinit= J ; j=j+3; x=y=z=13.0; Initialization int i=0; Binary operators Addition :+ Subtraction : - Multiplication : * Division : / Modulus : % // only works for integers values Unary operators +, - Integer division 1/2 = 0 (?), 3/2 = 1 (?)

2 Arithmetic ti operators In binary operators If two operands are int type : the result is int type If one or two operands are floating-point type : the result is floating-point it type = /5 12.0/5.0 0 = 2.4 increment/decrement t Increment operator ++ i=i+1; i+1 i++; // postfix form ++i; // prefix form decrement operator i=i-1; i--; // postfix form --I; // prefix form Difference between i++ and ++i? prefix vs. postfix Difference shows up when the operators are used as a part of a larger expression ++k : k is incremented before the expression is evaluated. k++ : k is incremented after the expression is evaluated. difference? int a; int b; int i=0, j=0; int i=0, j=0; a= (++i) + (++j); b= (i++) + (j++); General syntax Shorthand Operators variable = variable op expression; is equivalent to variable op= expression; Common forms +=, -=, *=, /=, %= Examples j=j*(3+x); j j *= 3+x; a=a/(s-5); a /= s-5;

3 Precedence, Associativity it of Operators Operator Precedence determines the order in which operations are performed operators with higher precedence are employed first. precedence 1 st unary +, unary - 2 nd binary * / % 3 rd binary + - Operator Associativity operators if two operators in an expression have the same precedence, associativity determines the direction in which the expression will be evaluated. *, /, % : L -> R +, - (bin): L -> R = : R -> L +, - (unary) : R -> L Precedence Examples Evaluation Order * 3-4 -> > 7-4 -> 3 use parenthesis to force a desired order of evaluation (1 + 2) * (3 4) Associativity it Examples Bitwise i Operators Left associativity a / b * c (a / b) * c Right associativity a - (+ (- a)) shift/lo gic shift op. bit op. Op. name usage type output left shift a<<n integer right shift a>>n integer Shift bits of a to left by nbit Newly created bits will be 0 Shift bits of a to right by n bit Newly created bits will be 0 bit AND a & b integer AND of a s and b s each bit bit OR a b integer OR of a s and b s each bit bit XOR a ^ b integer XOR of a s and b s each bit 1 s complement ~a integer 1 s complement of a

4 Truth/False Table Bitwise i Operators Examples a b a&b a b a^b a ~a = = << << 2 = = >> >> 3 = = 2 output: 11 << 2 = >> 3 = 2 expression value result a 0x1f b 0x31a ~a 0xe0fa a & b 0x output: 1f05 & 31a1 = f05 31a1 = 3fa5 1f05 ^ 31a1 = 2ea4 ~1f05 = ffffe0fa a b 0x3fa a ^ b 0x2ea

5 Relational l Operators meaning 연산자자료형결과값 Equal a == b not equal less than less than or equal to greater than a!= b a<b a <= b a > b integer or greater than a >= b or equal to 1(=true) if a is equal to b otherwise 0(=false) 1(=true) if a is not equal to b otherwise 0(=false) 1(=true) if a is less than b otherwise 0(=false) 1(=true) if a is less than or equal to b otherwise 0(=false) 1(=true) if a is greater than b otherwise 0(=false) 1(=true) if a is greater than or equal to b otherwise 0(=false) output: (10 > 11) = 0 (10 >= 11) = 0 (10 == 11) = 0 (10!= 11) = 1 (10 < 11) = 1 (10 <= 11) = 1 Logical Operators #include <stdio.h> op name expression meaing logical NOT! a If a is false, then 1(=true), otherwise 0(=false) logical AND logical OR a && b a b If both a and b are true, then 1(=true), otherwise 0(=false) If either a or b is true, then 1(=true), otherwise 0(=false) int main() { int score; printf("score?"); scanf("%d",&score); if (score >= 90 && score <=100) printf("your grade is A.\n"); if (score >= 80 && score < 90) printf("your grade is B.\n"); if (score >= 70 && score < 80) printf("your grade is C.\n"); if (score >=60 && score < 70) printf("your grade is D.\n"); if (score < 60) printf("your grade is F.\n"); } return 0;

6 Automatic ti Type Conversion Automatic ti Type Conversion What happens when expression has mixture of different data types. double x=1.2; float y=0 0.0; 0; int i=3; int j=0; j=x+i; /* (temporary copy of)i will be converted to double type before + operation. the value of i in memory is unchanged */ y=x+i; printf( j=%d, y=%f\n,j,y); lower types are promoted to higher types. The expression itself will have the type of its highest operand. The type hierarchy is as follows long double double float int short, char If either operand is long double, convert the other to long double Otherwise, if either operand is double, convert the other to double Otherwise, if either operand is float, convert the other to float Otherwise, convert char and short to int Automatic Type Conversion with assignment operator Example Type casting Programmers can enforce type conversion to a variable double x=5.5; int y=3; y=x; /* x will be converted to int type */ x=y; /* y will be converted to double type */ Ex1) double x=3.5; double y=2.7; double below_point; below_point = x*y - (int)(x*y) ; Ex2) double x=3.5; printf( integer number of x = %d\n,(int)x);
