In this program we input two number and check which number is smallest. For this, we give a condition As:- If 1st number is smallest then print 1st number else 2nd number is smallest and print 2nd number. #include<stdio.h> #include<conio.h> void main() { int a,b; clrscr(); printf("Enter 1st number="); scanf("%d",&a); printf("Enter 2nd number="); scanf("%d",&b); if(a<b) printf("\n1st number is smallest"); else printf("\n2nd number is smallest"); getch(); } OUTPUT   Enter 1st number=7 Enter 2nd number =10 1st number is smallest Related Examples  Write a program to input a number and check number is positive or not.

In this program we input two number and check which number is highest. For this, we give a condition As:- If 1st number is highest then print 1st number else 2nd number is highest and print 2nd number. #include<stdio.h> #include<conio.h> void main() { int a,b; clrscr(); printf("Enter 1st number="); scanf("%d",&a); printf("Enter 2nd number="); scanf("%d",&b); if(a>b) printf("\n1st number is highest"); else printf("\n2nd number is highest"); getch(); } OUTPUT   Enter 1st number=9 Enter 2nd number =7 1st number is highest Related Examples  Write a program to input a number and check number is positive or not.

In this program input a number and check number is positive, negative or nuteral. If number is greater than Zero then print positive , if less than zero then print negative and if both condition false then print nuteral. #include<stdio.h> #include<conio.h> void main() { int n; clrscr(); printf("Enter a number="); scanf("%d",&n); if(n>0) printf("Positive number"); else if(n<0) printf("Negative number"); else printf("Nuteral"); getch(); } OUTPUT  Enter a number=4 Positive number                Or Enter a number=-4 Negative number                Or Enter a number=0 Nuteral Related Examples  1.

In this program we input a number and check number is negative or not means if number is less than Zero then number is negative or not. #include<stdio.h> #include<conio.h> void main() { int n; clrscr(); printf("Enter a number="); scanf("%d",&n); if(n<0) printf("\nNegative number"); else printf("Not negative number"); getch(); } OUTPUT  You can follow me on Google+.

In this program we input a number and check number is positive or not. If number is greater than Zero, then number is positive. #include<stdio.h> #include<conio.h> void main() { int n; clrscr(); printf("Enter a number="); scanf("%d",&n); if(n>0) printf("Positive number"); else printf("Not positive number"); getch(); } Follow for recently updates. 

In this program we input three numbers and print their Reverse. First we find 1st digit by (n/100), 2nd digit by(n/10)%10 and 3rd digit by (n%10). Then finally we add a program logic. #include<stdio.h> #include<conio.h> void main() { int n,d1,d2,d3,r=0; clrscr(); printf("Enter three digit number="); scanf("%d",&n); d1=(n/100); d2=(n/10)%10; d3=n%10; r=(d3*100)+(d2*10)+d1; printf("\nReverse of number=%d",r); getch(); } OUTPUT 

In this program we input three numbers and print their sum of digit. First we find 1st digit by (n/100), 2nd digit by(n/10)%10 and 3rd digit by (n%10). Then finally sum of digits. #include<stdio.h> #include<conio.h> void main() { int n,d1,d2,d3,s=0; clrscr(); printf("Enter three digit number="); scanf("%d",&n); d1=(n/100); d2=(n/10)%10; d3=n%10; s=d1+d2+d3; printf("\nSum of digits=%d",s); getch(); } OUTPUT 

In this program input two digit number and print the sum of its digits. For this we find 1st digit by number/10 and 2nd digit by n%10 . In the end we multiply 2nd number to 10 and add 1st number. #include<stdio.h> #include<conio.h> void main() { int n,d1,d2,r=0; clrscr(); printf("Enter two digit number="); scanf("%d",&n); d1=n/10; d2=n%10; r=(d2*10)+d1; printf("\nReverse of number=%d",r); getch(); } OUTPUT 

In this program input two digit number and print the sum of its digits. For this we find 1st digit by number/10 and 2nd digit by n%10.  #include<stdio.h> #include<conio.h> void main() { int n,d1,d2,s=0; clrscr(); printf("Enter two digit number="); scanf("%d",&n); d1=n/10; d2=n%10; s=d1+d2; printf("\nSum of digits=%d",s); getch(); } OUTPUT 

/* Program to swap two number in C */ #include<stdio.h> #include<conio.h> void main() { int a,b; clrscr(); printf("Enter first number="); scanf("%d",&a); printf("Enter second number="); scanf("%d",&b); a=a+b; b=a-b; a=a-b; printf("\nFirst number=%d",a); printf("\nSecond number=%d",b); getch(); } OUTPUT  Note: If any problems in this program please comment and never forget to Share.

#include<stdio.h> #include<conio.h> void main() { int a,b,c=0; clrscr(); printf("Enter first number="); scanf("%d",&a); printf("Enter second number="); scanf("%d",&b); c=a; a=b; b=c; printf(\nFirst number=%d",a); printf("\nSecond number=%d",b); getch(); } OUTPUT Note:- If any problem in this program please comment and never forget to share.

#include<stdio.h> #include<conio.h> void main() { int a,b,c,m=0; clrscr(); printf("Enter three number="); scanf("%d%d%d",&a,&b,&c); d=(a+b+c)/3; printf("Average=%d",d); getch(); } OUTPUT  Note:- If you want to calculate floating value (value which contains point) or fractional value ,you can use "float " and "%f" replace to "int " and "%d". If you want to calculate both use "double".
