How many types of selection statements in c language?
there are two types of selection statements in c-language they are if-else and switch case.these two are known as selection statements,because their syntax is like this,if-else syntax:-if(condition){statements}else{statement}in the abow syntax it contains two blocks first one is if and second one is else in 'if' it fills with required condition if the condition is satisfied then it execute the if block,whether it is false it execute the else statements.switch case syntax:-switch(condition){case.1:statements;case.2:statements;case.3:statements;...case.n:statements;default:statement;}in abow switch case we can select any case and execute,in this selection statement gives the fiexibulity to the user.it contains default statement it shows the wrong selection in these cases.examples programs to these statements:-1.biggest of two numbers program?main(){int a,b,c;printf("enter a,b values");scanf(&a);scanf(&b);scanf(&c);if(a>b){printf("a is big");}else{printf("b is big");}}out put:-enter a,b values 8,5a is bigenter a,b values 3,9b is big2.perform arithmetic operation intwo numbers?main(){int a,b,c,d;printf("enter a,b values");scanf(&a);scanf(&b);scanf(&c);printf("enter your choice"&c);switch(c){case.1:d=a+b;printf("d value is"&d);case.2:d=a-b;printf("d value is"&d);case.3:d=a*b;printf("d value is"&d);default:printf("wrong selection");}}out put:-enter a,b values 6,5enter your choice 1d=11enter your choice 2d=1enter your choice 3d=30
How do you return to a main function?
..use do{} while{}..for example..#includemain(){int choose;double a,b,c;printf("Enter 7 if you want to use the calculator. Otherwise,type any character.\n");scanf("%d",&choose);do{if (choose==7){printf("Press 1 for addition.\n");printf("Press 2 for subtraction.\n");printf("Press 3 for multiplication.\n");printf("Press 4 for division.\n");scanf("%d",&choose);if (choose==1){printf("Enter the addends\n");scanf("%lf %lf", &a,&b);c=a+b,printf("The sum of %lf and %lf is %lf.\n",a,b,c);}else if(choose==2){printf("Enter the minuend and subtrahend\n");scanf("%lf %lf", &a,&b);c=a-b,printf("The difference of %lf and %lf is %lf.\n",a,b,c);}else if(choose==3){printf("Enter the multipliers\n");scanf("%lf %lf", &a,&b);c=a*b,printf("The product of %lf and %lf is %lf.\n",a,b,c);}else if(choose==4){printf("Enter the dividend and divisor\n");scanf("%lf %lf", &a,&b);c=a/b,printf("The quotient of %lf and %lf is %lf.\n",a,b,c);}else{printf("You have entered an invalid digit.\n");}printf("If you want to continue,press 7 and choose again from 1 to 4.\n");printf("Do you want to exit?
