C: Sum of two integer numbers.

Question:

Write a program to find the sum of two integer numbers.

Answer:

#include<stdio.h>
int main() {    

    int number1, number2, sum;
    
    printf("Enter First integers: ");
    scanf("%d", &number1);
    
    printf("Enter Second integers: ");
    scanf("%d", &number2);

    // calculating sum
    sum = number1 + number2;      
    
    printf("Sum of two numbers: %d + %d = %d \n", number1, number2, sum);
    return 0;
}

using namespace std;
bool isNumeric(string str) {
   for (int i = 0; i < str.length(); i++)
      if (isdigit(str[i]) == false)
      return false; //when one non numeric value is found, return false
   return true;
}
int main() {
   string str;

  C programme to print pyramid of triangle:

In this blog i am sharing some code, that will print pyramid of triangle and inverse.

1. Pyramid of triangle:

Code:

=====================

#include<stdio.h>

int main() {

    int i, j, rows;

    printf("Enter number of rows: ");

    scanf("%d", &rows);

    for (i=1; i<=rows; ++i)

   {

        for (j=1; j<=i; ++j)

       {

                                    printf("*");                                    

                    }

        printf("\n");

    }

    return 0;

}

=====================

Output:






2. Inverted pyramid of triangle:

Code:

======================

#include<stdio.h>

int main(){

                int a,b,c;

                printf("enter the value =");

                scanf("%d",&c);

                for(a=c; a>=1; a--)

                {

                                for(b=1; b<=a; b++)

                                {

                                                printf("*");

                                }

                                printf("\n");

             }

                return 0;             

}
