answer :-

as per your question,

explanation :-

This program uses only if statement to find the largest number.

Example #1

#include

INT main()

{

double n1, n2, N3;

printf("Enter three different NUMBERS: ");

scanf("%lf %lf %lf", &n1, &n2, &n3);

if( n1>=n2 && n1>=n3 )

printf("%.2F is the largest number.", n1);

if( n2>=n1 && n2>=n3 )

printf("%.2f is the largest number.", n2);

if( n3>=n1 && n3>=n2 )

printf("%.2f is the largest number.", n3);

return 0;

}

This program uses if...else statement to find the largest number.

Example #2

#include

int main()

{

double n1, n2, n3;

printf("Enter three numbers: ");

scanf("%lf %lf %lf", &n1, &n2, &n3);

if (n1>=n2)

{

if(n1>=n3)

printf("%.2lf is the largest number.", n1);

else

printf("%.2lf is the largest number.", n3);

}

else

{

if(n2>=n3)

printf("%.2lf is the largest number.", n2);

else

printf("%.2lf is the largest number.",n3);

}

return 0;

}

Example #3

#include

int main()

{

double n1, n2, n3;

printf("Enter three numbers: ");

scanf("%lf %lf %lf", &n1, &n2, &n3);

if( n1>=n2 && n1>=n3)

printf("%.2lf is the largest number.", n1);

else if (n2>=n1 && n2>=n3)

printf("%.2lf is the largest number.", n2);

else

printf("%.2lf is the largest number.", n3);

return 0;

}
