#include<stdio.h >
int main( ){
 int a, b;
 printf("Enter Values for A : ");
 scanf("%d",&a);
 printf("Enter Values for B : ");
 scanf("%d",&b);
 if(a>b) {
  printf("A is Greatest\n") ;
 }
 else {
  printf("B is Greatest\n");
 }
 return 0;
}
OUTPUT :

Enter Values for B : 119
B is Greatest

 C Program to find greatest among three numbers.

#include< stdio.h >
int main( ){
int a, b, c;
printf("Enter Values for A,B & C : ");
scanf("%d%d%d",&a,&b,&c);
if(a>b && a>c) {
printf("A is Greatest\n") ;
}
else if(b>c){
printf("B is Greatest\n");
}
else {
printf("C is Greatest\n");
}
return 0;
}
OUTPUT :

int a, b,c;
printf("Enter Values for A,B & C : ");
scanf("%d%d%d",&a,&b,&c);
if(a>b) {
if(a>c)
printf("A is Greatest\n") ;
else
printf("C is Greatest\n") ;
}
else {
if(b>c)
printf("B is Greatest\n") ;
else
printf("C is Greatest\n") ;
}
return 0;
}
OUTPUT :

  printf("Character is VOWEL\n");
 }
 else if(a=='A'||a=='E'||a=='I'||a='O'||a=='U') {
  printf("Character is VOWEL\n");

Character is NOT VOWEL

 C Program to ask user to enter marks of 5 subjects and calculate percentage then print GRADE according to marks in percentage.

int main( ) {
 int m1,m2,m3,m4,m5;
 float per;
 printf("Enter Marks Subject 1: ");
 scanf("%d",&m1);
 printf("Enter Marks Subject 2: ");
 scanf("%d",&m2);
 printf("Enter Marks Subject 3: ");
 scanf("%d",&m3);
 printf("Enter Marks Subject 4: ");
 scanf("%d",&m4);
 printf("Enter Marks Subject 5: ");
 scanf("%d",&m5);
 per = (m1+m2+m3+m4+m5)/5.0f;
 printf("YOUR PERCENTGE : %f\n",per);
 if(per>=70){
  printf("YOUR GRADE IS : A\n");
 }
 else if(per>=60){
  printf("YOUR GRADE IS : B\n");
 }
 else if(per>=50){
  printf("YOUR GRADE IS : C\n");
 }
 else if(per>=40){
  printf("YOUR GRADE IS : D\n");
 }
 else{
  printf("YOUR GRADE IS : FAIL\n");
 }
 return 0;
}
OUTPUT :
Enter Marks Subject 1: 55
Enter Marks Subject 2: 67
Enter Marks Subject 3: 50
Enter Marks Subject 4: 68
Enter Marks Subject 5: 78
YOUR PERCENTAGE : 63.60
YOUR GRADE IS : B
