用各类程序语言写99乘法表

Python:

for i in range(1, 10):
    for j in range(1, i+1):
        print(f"{j}x{i}={i*j}", end="\t")
    print()

Java:

for (int i = 1; i <= 9; i++) {
    for (int j = 1; j <= i; j++) {
        System.out.print(j + "x" + i + "=" + (i*j) + "\t");
    }
    System.out.println();
}

C++:

for (int i = 1; i <= 9; i++) {
    for (int j = 1; j <= i; j++) {
        cout << j << "x" << i << "=" << (i*j) << "\t";
    }
    cout << endl;
}

JavaScript:

for (let i = 1; i <= 9; i++) {
    for (let j = 1; j <= i; j++) {
        console.log(`${j}x${i}=${i*j}\t`);
    }
    console.log("\n");
}

PHP:

for ($i = 1; $i <= 9; $i++) {
    for ($j = 1; $j <= $i; $j++) {
        echo $j . "x" . $i . "=" . ($i*$j) . "\t";
    }
    echo "\n";
}

以上仅是简单的实现，还有其他语言的实现方式。
