paizaラーニングレベルアップ問題集の【出力形式を指定して出力】をやってみました。

問題
2つの文字列を出力

文字列とN個の整数の出力

九九表を罫線入りで出力

ペアの数値の入った表を罫線入りで出力

ペアの数値の入った表を罫線入りで出力2

3～5問目は予め横幅を計算してその回数分=を出力するという考え方もありますが、今回は1行目を出力する際に横幅を計算するようにしたいと思います。
ちなみに、

  • 3問目　$42$文字
  • 4問目　$9\times W-3$文字
  • 5問目　$25\times W-3$文字

です。

参考

N倍の文字列

C
2つの文字列を出力
#include <stdio.h>

int main() {

	printf("%s + %s = %s%s\n", s, t, s, t);
	return 0;
}
文字列とN個の整数の出力
#include <stdio.h>

int main() {
	int n, a, b;
	scanf("%d %d %d", &n, &a, &b);
