Switch Statement switch(){ case ’A’: statement; break; case ‘B’: statement; break; default: statement; break; } 3

Example Fig. 5. 10 p. 177~179 4

while and do. . while loop statements • while(condition) statement; • do{ statement; } while(conditions); e. g. , int a =1 ; while(a<=10) cout << a; a++; e. g. , int a=1; do { cout <<a; a++; } while(a<=10); 5

More on while loop • int a=1, total=0; do { total+=a++; } while(a<=10); counter-controlled loop • int a=1, total=0; do { cin >>a; total+=a; } while(a!=-1); Sentinel controlled loop 6

for Loop Statement • for(initialization; condition; inc/dec) statement; e. g. , for(int a=1; a<=10; a++) cout << a; e. g. , for(int i=1, j=10; i<=j; i++, j--) cout << i+j; 7

More Examples on for Loop • for statement examples o vary control variable from 1 to 100 in increments of 1 • for(int i=1; i<=100; i++) o vary control variable from 100 to 1 in increments of -1 • for(int i=100; i>=1; i--) o vary control variable from 7 to 77 in steps of 7 • for(int i=7; i<=77; i+=7) o vary control variable from 20 to 2 in steps of -2 • for(int i=2; i>=2; i-=2) o vary control variable over the sequence 2, 5, 8, 11, 14, 17, 20 • for(int i=2; i<=20; i+=3) o vary control variable over the sequence 99, 88, 77, 66, 55, 44, 33, 22, 11, 0 • for(int i=99; i>=0; i-=11) 8

An Example Using for Statement • Fig. 5. 6 on page 195 o a = p (1+r)^n; • Standard library function std: : pow o Calculates an exponent o Example • pow(x, y) o Calculates the value of x raised to the yth power o Requires header file <cmath> 9
