sum = 15 Input: Enter value of N: 10 Logic/formula: sum = N*(N+1)/2 = 10*(10+1)/2 =10*11/2 = 110/2 = 55 Output: sum = 55 C program to find sum of all numbers from 0 to N without using loop #include<stdio.h>intmain(void){intn,sum;//input value of nprintf("Ent...
Write a C program that uses a while loop to calculate and print the sum of the even integersfrom 2 to 30. 相关知识点: 试题来源: 解析 #include int main() { int sum = 0; int i = 2; while (i <= 30) { sum += i; i += 2; } printf("Sum of even integers from 2 to 30 ...
The above program takes input from the user and stores it in the variable n. Then, for loop is used to calculate the sum up to n. Sum of Natural Numbers Using while Loop #include <stdio.h> int main() { int n, i, sum = 0; printf("Enter a positive integer: "); scanf("%d",...
一、输出菱形 输出类似于下图的菱形: 通过分析:1、先分为上下两部分输出 2.在输出前先输出空格 3.找规律进行输出 可知,可令上半部分line行,下半部分便是line-1行。 找空格的规律:当line为7时,第一行有6个空格,第二行有5个……第七行没有 起始点便是line-1,终止为0 ...
Program to find the sum of two integer numbers using command line arguments in C #include<stdio.h>intmain(intargc,char*argv[]){inta,b,sum;if(argc!=3){printf("please use\"prg_name value1 value2\"\n");return-1;}a=atoi(argv[1]);b=atoi(argv[2]);sum=a+b;printf("Sum of%d,%d...
我们再来看另一个宏定义:#definesum(a, b) a + b 当我们有如下宏调用时就会出错intresult_sum = sum(3,5) * sum(2,3);因为宏展开变成了 3 + 5 * 2 + 3,由于*优先级高于+,所以程序输出result_sum:16 我们将宏改为#definesum(a, b) ((a) + (b))就可以避免出现上面的错误。
#include<stdio.h>intmain(){int num1=0;int num2=0;int sum=0;printf("请输入两个操作数:->");scanf("%d %d",&num1,&num2);sum=num1+num2;printf("sum=%d\n",sum);return0;} 变量的作用域和生命周期 作用域: 一段程序的代码并不总是有效的,限定这个名字的可用性的代码就是这个名字的作用...
Finally, the value of sum is printed on the screen. The program output is shown below: #include<stdio.h>void main(){ int n,j,sum=0; clrscr(); printf("Enter the Number : "); scanf("%d",&n); for(j=1;j<=n;j++) { printf("%d ",j); sum=sum+j; } printf("\nSum of ...
