#include &stdio.h& main() {x=11/3;int y=5;printf(&%%d,%%%d\n&,x,y);}求输出为什么是%d,%3 ?_百度知道

#include &stdio.h& main() {x=11/3;int y=5;printf(&%%d,%%%d\n&,x,y);}求输出为什么是%d,%3 ?
%%输出%，所以%%d输出%d%%%d，前两个百分号输出%后边的%d输出x的值3，整个输出是%3x的值：x是整型数据11/3仅输出结果的整数部分
y呢？没有格式说明它不输出吗？

AbstractA novel yellow phosphor called Y6+(x/3)-yCay+(z/2)Si11N20+x-y+zO1-x+y-z:Ce that has an intensive blue excitation band was discovered. This phosphor, which can be synthesized relatively easily because it does not require high pressure or temperature, can be gained by firing at 1600.C for 4 hours under H2 5% + N2 95% gas flow. Rietveld refinement and SEM-EDX analysis revealed that the structure of Y6+(x/3)-yCay+(z/2)Si11N20+x-y+zO1-x+y-z:Ce is composed of a unique extensive (about 70%) substitution of Ca-O bonds for Y-N bonds in the Y6+(x/3)Si11N20-xO1+x structure having a triclinic lattice in the P31c space group. Y6+(x/3)-yCay+(z/2)Si11N20+x-y+zO1-x+y-z:Ce has shown yellow emission at 554 nm with 450-nm excitation and an FWHM of 147 nm. The wavelength of the excitation peak is 450 nm, which coincides with the wavelength of blue LED light. Due to having a broad yellow emission and an excitation band suitable for blue LED, the discovered phosphor is expected to be used in general lighting devices requiring high color rendering. The conditions for stably substituting Ca-O bonds for Y-N bonds are discussed.Do you want to read the rest of this article?Request full-text
