1:-Write a program to get two integers from the user and print the sum of the two integers?
#include<stdio.h>
void main()
{
    int a,b;
    printf("enter two numbers:");
    scanf("%d%d",&a,&b);
    
    printf("the sum of two numbers:%d",(a+b));
}



2:-Write a function to add two integers. 
#include<stdio.h>
int sum(int a, int b);
void main()
{
    int a,b,add;
    printf("\n enter the numbers:");
    scanf("%d%d",&a,&b);
    
    add=sum(a,b);
    printf("sum=%d",add);
    
}
3:-Write a program to get two float from the user and print the sum of the two float?
#include<stdio.h>
void main()
{
    float a,b;
    printf("enter two numbers:");
    scanf("%f%f",&a,&b);
    
    printf("%f",a+b);
}


4:-Write a function to add two float.
#include<stdio.h>
float sum(float a,float b);
void main()
{
    float a,b,add;
    printf("enter the numbers:");
    scanf("%f%f",&a,&b);
    
    add=sum(a,b);
    printf("total=%f",add);
    
}

float sum(float a,float b)
{
    float result;
    result=a+b;
    return result;
}




5:-Write a function to compare 2 numbers and test it.
#include<stdio.h>
int compare(int a,int b);
void main()
{
    int a,b,large;
    printf("enter the numbers:");
    scanf("%d%d",&a,&b);
    
    large=compare(a,b);
    printf("largest=%d",large);
    
}

int compare(int a,int b)
{
    if(a>b)
    return a;
    else
    return b;
}






6:-Write a function to compare 3 numbers and test it.
#include<stdio.h>
int compare(int a,int b,int c);
void main()
{
    int a,b,c,large;
    printf("enter the numbers:");
    scanf("%d%d%d",&a,&b,&c);
    
    large=compare(a,b,c);
    printf("largest=%d",large);
    
}

int compare(int a,int b,int c)
{
    if(a>b && a>c)
    return a;
    if(b>a && b>c)
    return b;
    else
    return c;
}
