Job 1:

Requirement: Output a rectangle composed of * symbols. Each line must have 50 *, and a total of 60 lines are required. Use a dual for loop.

Job 2:

Requirement: Output a triangle composed of * symbols. The first line is required to be a *, the second line is two * The third line is three *, and the last line is 10 *. Use a dual for loop.

Job 3:

Requirement: Output a triangle composed of * symbols, which requires 10 characters in the first line *, 9 in the second line * 8 in the third line *, and 1 in the last line *. Use a dual for loop.

Job 4:

Requirement: Use a double-layer for loop to complete the following triangles

5 4 3 2 1

5 4 3 2

5 4 3

5 4

5

#include <iostream>using namespace std;int main(){    for(int i=1;i<=5;i++){        for(int j=5;j>=i;j--){            cout<<j;        }    cout<<endl;    }    return 0;}

Job 5:

Requirement: Output multiplication tips, which are completed using a dual for Loop

1*1 = 1

1*2 = 2 2*2 = 4

1*3 = 3 2*3 = 6 3*3 = 9

1*4 = 4 2*4 = 8 3*4 = 12 4*4 = 16

1*5 = 5 2*5 = 10 3*5 = 15 4*5 = 20 5*5 = 25

#include <iostream>using namespace std;int main(){for(int i=1;i<=9;i++){for(int j=1;j<=i;j++){cout<<j<<"*"<<i<<"="<<j*i<<"\t";}cout<<endl;}return 0;}

What is the difference between break and continue?

What is the output result of the program?

#include <iostream>using namespace std;int main(){    for(int i=0;i<3;i++){        cout<<"i="<<i;        continue;        }        }    return 0;}

View output results?

#include <iostream>using namespace std;int main(){    for(int i=0;i<3;i++){        if(i==2){            break;        }        cout<<"i="<<i<<endl;        }        return 0;}

What is the output result?

#include <iostream>using namespace std;int main(){    for(int i=0;i<18;i++){        if(i%2==0){            continue;        }        cout<<"i="<<i<<endl;        }        return 0;}
