5 if (number > 0) { 6 printf("The number is positive.\n"); 7 } else if (number < 0) { 8 printf("The number is negative.\n"); 9 } else { 10 printf("The number is zero.\n"); 11 } 12 return 0; 13} In this program, the number is evaluated against three conditions to...
Menu Selection: Interactive menus benefit from “if-else” statements. In a basic calculator program, users can choose an operation by entering a number, and the program responds accordingly: int choice; printf("Select operation:\n1. Addition\n2. Subtraction\n3. Multiplication\n4. Division\n");...
C/C++ if else statement with ExamplesC/C++ 中的决策制定 有助于编写决策驱动语句和根据特定条件执行一组特定的代码。if 语句单独告诉我们,如果条件为真,它将执行一个语句块,如果条件为假,则不会。但是,如果条件为假,我们想做其他事情怎么办。这里是 C/C++ else 语句。当条件为假时,我们可以使用 else 语句...
Lets take the same example that we have seen above while discussing nested if..else. We will rewrite the same program using else..if statements. #include<stdio.h>intmain(){intvar1,var2;printf("Input the value of var1:");scanf("%d",&var1);printf("Input the value of var2:");scan...
So, in C if-else statement, we have an if block followed by else block. If the condition is true, if block is executed, and if the condition is false, else
else if (ch == ')') { while (s[top] != '(') postfix[k++] = pop(); elem = pop(); /* Remove ( */ } else { /* Operator */ while (pr(s[top]) >= pr(ch)) postfix[k++] = pop(); push(ch); } } while (s[top] != '#') /* Pop from stack till empty */ ...
Example 3: C if...else Ladder // Program to relate two integers using =, > or < symbol#include<stdio.h>intmain(){intnumber1, number2;printf("Enter two integers: ");scanf("%d %d", &number1, &number2);//checks if the two integers are equal.if(number1 == number2) {printf("...
The statement(s) under the ‘if’ condition is ignored from execution. For example: Examples Let’s take an example of a Boolean expression with the help of actual coding in C: If the condition is met (true) as per the given logical expression, then the program will print the statements...
The above two code examples emphasize the fact that when there are more than one statements in the if or else else, they must be put in curly brackets.To be safe, it is always better to use curly brackets even for a single statement. In fact, it improves the readability of the code....
if(j<n-i) printf(" "); else printf("%c",ch); } printf("\n"); } return 0; } Output: 1 2 3 4 5 6 7 8 9 10 11 12 Enter number of rows: 5 Enter the symbol: * *** *** *** *** *** ** ** * * * * ** ** *** *** *** *** *** Using While Loop...
