How This Works (C Code Logic)

\n

This calculator demonstrates a basic C program structure. The user inputs two numbers and selects an operation. The program uses a switch statement to check the selected operation and perform the corresponding arithmetic.

\n

\n#include <stdio.h>\nint main() {\n    char operator;\n    double num1, num2, result;\n    printf(\"Enter an operator (+, -, *, /): \");\n    scanf(\"%c\", &operator);\n    printf(\"Enter two numbers: \");\n    scanf(\"%lf %lf\", &num1, &num2);\n    switch(operator) {\n        case '+': result = num1 + num2; break;\n        case '-': result = num1 - num2; break;\n        case '*': result = num1 * num2; break;\n        case '/': \n            if (num2 != 0) result = num1 / num2; \n            else { printf(\"Error! Division by zero.\\n\"); return 1; }\n            break;\n        default: printf(\"Invalid operator.\\n\"); return 1;\n    }\n    printf(\"Result: %.2lf\\n\", result);\n    return 0;\n}\n
