Write a program in c for arithmetic operators by using switch case?
#include<stdio.h> #include<conio.h> void main() { int a,b,c; int menu; printf("choose the arithmetic option\n"); scanf("%d",&menu); switch(menu) { case 1: printf("Enter The Two Numbers:\n"); scanf("%d%d",&a,&b); c=a+b; printf("The addition of two numbers %d\n",c); break; case 2: printf("Enter THE TWO NUMBERS:\n"); scanf("%d%d",&a,&b); c=a-b; printf("The subtraction of two numbers %d\n",c); break; case 3: printf("Enter THE TWO NUMBERS:\n"); scanf("%d%d",&a,&b); c=a*b; printf("The multiplication of two numbers %d\n",c); break; case 4: printf("Enter THE TWO NUMBERS:\n"); scanf("%d%d",&a,&b); c=a/b; printf("The division of two numbers %d\n",c); break; } getch(); }
Greatest of four numbers if else if?
#include <stdio.h> #include <conio.h> int main() { int a,b,c,d; printf("Enter any 4 numbers"); scanf("%d%d%d%d",&a,&b,&c,&d); if(a>b&&a>c) { else if(a>d) printf("%d is greatest",a); } if(b>a&&b>c) { else if(b>d){ printf("%d is greatest",b); } if(c>a&&c>b) { else if(c>d) printf("%d is greatest",c); } else { printf("%d is greatest",d); } }
Conversion of binary to decimal in turbo c?
main() { int i,c=0,sum=0; scanf("%d",&i); while(i>=0) { i=i%2; sum=sum+i*pow(10,c); i=i/2; c++ } printf("%d",sum); } OR =) #include<stdio.h> #include<conio.h> void showbits(int h) { if(h==1) printf("%d",h); else { showbits(h/2); printf("%d",h%2); } } void main() { int nu; void showbits(int h); clrscr(); printf("Num?");scanf("%d",&nu); printf("\nBin eq of %d is ",nu); showbits(nu); getch(); }
C plus plus program that convert decimal to binary using the concept of stack?
#include<stdio.h> #include<stdlib.h> main() { int number,binary[10000],b=0; printf("Enter decimal number "); scanf("%d",&number); printf("\nBinary: "); for(;number;number/=2,b++) binary[b]=number%2; for(b--;b>-1;b--) printf("%d ",binary[b]); }
C program to find numbers divisible by 7?
#include<stdio.h> #include<conio.h> void main() { int i,c,n; printf("Enter the number of terms you want which are divisible by 7"); scanf("%d",&n); c=0; for(i=7;;i+=7) { printf("\n %d ",i); c++; if(c==n) break; } getch(); }

Exchange to interchange in two var in c program?
#include#includevoid main(){ int a,b,c;printf("\nEnter 1st no.");scanf("%d",&a);printf("\nEnter 2nd no.");scanf("%d",&b);c=a;a=b;b=c;printf("\n1st no.",a);printf("\n2nd no.",b);getch();}
How do the IO facilities in C plus plus differ from those in C?
The C standard library IO facilities are not extensible. For instance, the printf() and scanf() functions cannot handle user-defined types. However, the C++ standard library provides IO streams with insertion and extraction operators (<< and >>) that can be overloaded to support any user-defined type.
Write a program to find the largest of three numbers and print the output in ascending order?
void main() { int a,b,c; clrscr(); printf("Enter the value of a:"); scanf("%d",&a); printf("\nEnter the value of b:"); scanf("%d",&b); printf("\nEnter the value of c:"); scanf("%d",&c); if(a>b) { if(a>c) { if(b>c) { printf("c is smallest\n"); printf("b is middle\n"); printf("a is largest\n"); } else { printf("b is smallest\n"); printf("c is middle\n"); printf("a is largest\n"); } } else { printf("b is smallest\n"); printf("a is middle\n"); printf("c is largest\n"); } } else if(b>c) { if(a>c) { printf("c is smallest\n"); printf("a is middle\n"); printf("b is largest\n"); } else { printf("a is smallest\n"); printf("c is middle\n"); printf("b is largest\n"); } } else { printf("a is smallest\n"); printf("b is middle\n"); printf("c is largest\n"); } getch(); }
Define the role of printf and scanf in c language?

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? Enter any key.\n");scanf("%d",&choose);}}while(choose==7);}
