program to use sum of digits of any number in c language

#include <stdio.h>
int main()
{
    int n, sum = 0, rem;
    printf("enter a number : ");
    scanf("%d", &n);
    while (n > 0)
    {
        rem = n % 10;
        sum += rem;
        n /= 10;
    }
    printf("sum of digits = %d\n", sum);
    return 0;
}

output

enter a number : 55
sum of digits = 10

program to use floating arithmetic operator c language

#include<stdio.h>
int main()
{
    float a=12.4,b=3.8,s;
    s=a+b;
    printf("sum=%.2f\n",s);
    s=a-b;
    printf("difference=%.2f\n",s);
    s=a*b;
    printf("product=%.2f\n",s);
    s=a/b;
    printf("a/b=%.2f\n",s);
    return 0;
}

output

sum=16.20
difference=8.60
product=47.12
a/b=3.26

Steps Description

1. Declare float three variable a , b and s
2. Initialize in float variable a=12.4 b=3.8
3. Assign S variable with sum of variable a and b
4. printf inbuild function display S variable with decimal placeholder %d
5. Assign S variable with difference of variable a and b
6. printf inbuild function display S variable with decimal placeholder %d
7. Assign S variable with product of variable a and b
8. printf inbuild function display S variable with decimal placeholder %d
9. Assign S variable with a/b of variable a and b
10. printf inbuild function display S variable with decimal placeholder %d

program to use while loop is c language

#include <stdio.h>
int main()
{
    int i = 1;
    while (i <= 10)
    {
        printf("%d\t", i);
        i = i + 1;
    }
    printf("\n");
    return 0;
}

output

1       2       3       4       5       6       7       8       9       10

Steps Description

1. Declare integer variable i
2. initialize integer variable i=1
3. whil (i=5) condition which needs to be evaluated
4. printf inbuild function to display the value of %d
5. code of instructions which need to be executed
6. i++ increment value

program to use quotient and remainder in c language

 #include<stdio.h>
int main()
{
    int x,y,quo,rem;
    printf("Enter two number : ");
    scanf("%d%d",&x,&y);
    if(y)
    {
        quo=x/y;
        rem=x%y;
        printf("quotient = %d,remainder=%d\n",quo,rem);
    }
    else 
    printf("divide by zero error\n");
    return 0;
}

output

Enter two number : 65
5
quotient = 13,remainder=0

program to use size of operators in c language

#include<stdio.h>
int main()
{
    int var;
    printf("size of int =%u\n",sizeof(int));
    printf("size of float=%u\n",sizeof(float));
    printf("size of var=%u\n",sizeof(var));
    printf("size of an integer constant=%u\n",sizeof(45));
    return 0;

}

output

size of int =4
size of float=4
size of var=4
size of an integer constant=4

Steps Description

1. Declare integer variable var
2. printf inbuild function to display size of integer variable "var" using another inbuild function "size of()
3. printf inbuild function to display size of float variable "var" using another inbuild function "size of()
4. printf inbuild function to display size of"var" variable using another inbuild function size of()
5. printf inbuild function to display size of in integer variable "var" using another function size of()
