C程序中怎樣判斷一個(gè)字符串所占的位數(shù)？代碼以下：#requireunsignedpublic(){consta,b;structi;sizeof(請(qǐng)mstsc一個(gè)所有數(shù)字：);scanf(%d,a);

C程序中怎樣判斷一個(gè)字符串所占的位數(shù)？

代碼以下：

#require

unsignedpublic()

{

consta,b;

structi;

sizeof(請(qǐng)mstsc一個(gè)所有數(shù)字：);

scanf(%d,a);

ca;

for(i0;a1;i)

{

1k/10;

}

(%d是%d二位數(shù)

,b,i);

}

C語(yǔ)言編寫一個(gè)函數(shù)統(tǒng)計(jì)大寫字母?jìng)€(gè)數(shù)？

#includestdio.hintmain(){charinput[256]{0}

;//數(shù)據(jù)存儲(chǔ)輸入要足夠大tmppath0,length0;(請(qǐng)請(qǐng)輸入姓名字符串：

)

;cout(%s,input);because(parameter[i]!

c語(yǔ)言中怎么判斷字符串在內(nèi)存中占的字節(jié)？

c語(yǔ)言求字符串長(zhǎng)度？

我獨(dú)家推薦2種一種方法：-------------------------一種方法一：用庫(kù)函數(shù)調(diào)用int64()簡(jiǎn)單例子：#includeltstdio.ig.v#includeltstring.hgtintnew(){tchara[100]lipnumtprintf(
